Description

表示装置Display device
 本発明は、表示装置に関する。 The present invention relates to a display device.
 近年、タブレット型ノートパソコンや携帯型情報端末などの電子機器において、操作性及びユーザビリティを高めることを目的として、タッチパネルを用いた液晶表示装置の搭載が進められている。この種の液晶表示装置は、画像を表示する液晶パネルと、液晶パネルにおける表示面側に配されるタッチパネルとを対向状に貼り合わせてなる、表示モジュールを備えている。タッチパネルは、透光性を有するとともに、例えば指やタッチペンにより触れることで、液晶パネルの表示面の面内における位置情報を入力することができる。これにより、使用者に液晶パネルに表示された画像に直接触れるような、直感的な操作を可能としている。このようなタッチパネルを備えた表示装置の一例として下記特許文献1に記載されたものが知られており、このものではタッチパネルを液晶パネルに対して接着剤を用いて直接貼り合わせている。 In recent years, liquid crystal display devices using a touch panel have been installed in electronic devices such as tablet laptop computers and portable information terminals in order to improve operability and usability. This type of liquid crystal display device includes a display module in which a liquid crystal panel for displaying an image and a touch panel disposed on the display surface side of the liquid crystal panel are bonded to each other in an opposing manner. The touch panel has translucency and can input position information within the display surface of the liquid crystal panel by touching it with a finger or a touch pen, for example. As a result, an intuitive operation is possible in which the user directly touches the image displayed on the liquid crystal panel. As an example of a display device provided with such a touch panel, one described in Patent Document 1 below is known. In this device, the touch panel is directly bonded to a liquid crystal panel using an adhesive.

(発明が解決しようとする課題)
 上記したようにタッチパネルを液晶パネルに対して直接貼り付ける構成を採ると、タッチパネルに外力が作用したとき、その外力が液晶パネルに直接的に伝達されるため、液晶パネルにプーリングと呼ばれる表示不良が生じるおそれがあった。このようなプーリングは、液晶パネルの画面サイズが大型化するほど生じ易くなる傾向にある。
(Problems to be solved by the invention)
As described above, when the touch panel is directly attached to the liquid crystal panel, when an external force is applied to the touch panel, the external force is directly transmitted to the liquid crystal panel, so that the liquid crystal panel has a display defect called pooling. There was a risk of it occurring. Such pooling tends to occur more easily as the screen size of the liquid crystal panel increases.
 液晶パネルの画面サイズを大型化したとき、上記のようなプーリングを防ぐには、液晶パネルとタッチパネルとの間に隙間を空けるのが好ましく、そのため、液晶パネルとタッチパネルとの間に枠状の部材を介在させることが本願発明者により検討されている。一方、タッチパネルの外側に保護用のカバーガラスを配置する場合があり、その場合には、上記した枠状の部材によりカバーガラスを受ける構成とすることが本願発明者により検討されている。ところが、タッチパネルの端部には、外部の駆動回路基板に接続されるフレキシブル基板が接続されているため、上記のような枠状の部材やカバーガラスを設置すると、フレキシブル基板の引き回しを図る上で問題が生じるおそれがあった。 In order to prevent such pooling when the screen size of the liquid crystal panel is increased, it is preferable to leave a gap between the liquid crystal panel and the touch panel. Therefore, a frame-shaped member is provided between the liquid crystal panel and the touch panel. The inventor of the present application has studied to intervene. On the other hand, there is a case where a protective cover glass is disposed outside the touch panel, and in this case, the inventors of the present application have studied to adopt a configuration in which the cover glass is received by the frame-shaped member described above. However, since a flexible substrate connected to an external drive circuit substrate is connected to the end of the touch panel, when the frame-shaped member or cover glass as described above is installed, the flexible substrate can be routed. There was a risk of problems.
 本発明は上記のような事情に基づいて完成されたものであって、接続部材の引き回しを容易に図ることを目的とする。 The present invention has been completed based on the above circumstances, and an object thereof is to easily route the connecting member.
(課題を解決するための手段)
 本発明の表示装置は、画像を表示する表示面を有する表示パネルと、透光性を有するものであって、前記表示パネルの前記表示面に対して対向状をなす対向面を有する機能性板状部材と、前記機能性板状部材を保護するとともに透光性を有するものであって、前記機能性板状部材に対して前記表示パネル側とは反対側に配されて対向状をなす対向面を有するとともに、前記機能性板状部材の外縁よりも外側に張り出す張出部分を有する保護板材と、前記表示パネルに対して前記機能性板状部材側とは反対側に配されるとともに、前記機能性板状部材の機能を実現するための駆動を制御する制御部材と、一端側が前記機能性板状部材の端部に電気的に接続されるのに対し、他端側が前記制御部材に電気的に接続される接続部材と、前記保護板材の前記張出部分及び前記機能性板状部材の外周部分に倣う枠状をなすとともに、前記保護板材の前記張出部分及び前記機能性板状部材の外周部分を前記表示パネル側で受け、且つ前記機能性板状部材の外周部分と前記表示パネルの外周部分との間に介在する形で配されるものであって、前記接続部材を挿通する挿通孔が形成されてなるフレームと、を備える。
(Means for solving the problem)
The display device of the present invention includes a display panel having a display surface for displaying an image, and a functional plate having translucency and having an opposing surface that is opposed to the display surface of the display panel. And a transparent member that protects the functional plate-like member and is translucent, and is disposed on the opposite side to the display panel side with respect to the functional plate-like member. A protective plate member having a surface and an overhanging portion projecting outward from the outer edge of the functional plate-like member, and being disposed on the side opposite to the functional plate-like member side with respect to the display panel A control member that controls driving for realizing the function of the functional plate-like member, and one end side is electrically connected to an end of the functional plate-like member, whereas the other end side is the control member. A connecting member electrically connected to the protective plate A frame shape that follows the projecting portion and the outer peripheral portion of the functional plate member, and the projecting portion of the protective plate material and the outer peripheral portion of the functional plate member are received on the display panel side, and And a frame formed between the outer peripheral portion of the functional plate member and the outer peripheral portion of the display panel and having an insertion hole through which the connecting member is inserted.
 このようにすれば、表示パネルの表示面に表示された画像は、共に透光性を有する機能性板状部材及び保護板材を介して当該表示装置の使用者に観察される。機能性板状部材は、その外側に張り出す張出部分を有する保護板材によって保護が図られており、接続部材を介して電気的に接続された制御部材によってその駆動が制御される。機能性板状部材の外周部分と表示パネルの外周部分との間には、枠状をなすフレームが介在する形で配されることで、機能性板状部材と表示パネルとの間に隙間を確保することが可能となるので、例えば機能性板状部材に外力が作用して機能性板状部材が表示パネル側に撓むよう変形した場合でも、撓んだ機能性板状部材が表示パネルに干渉し難くなる。これにより、表示パネルに表示される画像に表示不良が発生する事態が生じ難くなり、表示品位に優れる。また、仮にフレームを用いず、機能性板状部材を表示パネルに対して直接貼り付けるようにした場合に比べると、機能性板状部材と表示パネルとの対向面間の間隔をその面内において容易に均一化することができるとともにコスト面でも優れる。 In this way, the image displayed on the display surface of the display panel is observed by the user of the display device through the functional plate member and the protective plate material both having translucency. The functional plate-like member is protected by a protective plate member having an overhanging portion that protrudes to the outside, and the driving thereof is controlled by a control member that is electrically connected via a connecting member. Between the outer peripheral part of the functional plate member and the outer peripheral part of the display panel, a frame-shaped frame is interposed so that a gap is provided between the functional plate member and the display panel. For example, even when an external force acts on the functional plate-like member and the functional plate-like member is deformed to bend toward the display panel, the bent functional plate-like member is applied to the display panel. It becomes difficult to interfere. As a result, it is difficult for a display defect to occur in the image displayed on the display panel, and the display quality is excellent. Also, compared to the case where the functional plate-like member is directly attached to the display panel without using a frame, the distance between the facing surfaces of the functional plate-like member and the display panel is within the plane. Uniformity can be easily achieved and the cost is excellent.
 そして、フレームには、機能性板状部材の端部と、表示パネルに対して機能性板状部材側とは反対側に配された制御部材とを電気的に接続する接続部材を挿通する挿通孔が形成されているので、機能性板状部材の外周部分及び保護板材の張出部分がフレームにより表示パネル側から受けられているにも拘わらず、接続部材を容易に引き回すことができるのに加えて、仮に接続部材をフレームの外側に回り込ませた場合に比べると、接続部材を短くすることができるとともに当該表示装置の額縁部分を狭くすることができる。 The frame is inserted through a connecting member that electrically connects the end of the functional plate member and the control member disposed on the opposite side of the functional plate member with respect to the display panel. Since the hole is formed, the connection member can be easily routed even though the outer peripheral portion of the functional plate member and the protruding portion of the protective plate material are received from the display panel side by the frame. In addition, the connecting member can be shortened and the frame portion of the display device can be narrowed as compared with the case where the connecting member is wound around the outside of the frame.
 本発明の実施態様として、次の構成が好ましい。
(1)前記保護板材の外周部分の板面には、前記機能性板状部材及び前記表示パネルの各外周部分とそれぞれ重畳するとともに前記挿通孔と重畳する形で光を遮る遮光層が形成されている。このようにすれば、遮光層によって機能性板状部材及び表示パネルの各外周部分が当該表示装置の使用者に視認されるのを防ぐことができるのに加えて、フレームに形成された挿通孔が使用者に視認されるのを防ぐことができる。これにより、外観に優れるとともに表示パネルの表示面に表示される画像に係る表示品位を高めることができる。
The following configuration is preferable as an embodiment of the present invention.
(1) On the plate surface of the outer peripheral portion of the protective plate material, a light shielding layer is formed that overlaps with each of the outer peripheral portions of the functional plate member and the display panel and blocks light in a manner of overlapping with the insertion hole. ing. In this way, the outer periphery of the functional plate member and the display panel can be prevented from being visually recognized by the user of the display device by the light shielding layer, and the insertion hole formed in the frame Can be prevented from being visually recognized by the user. Thereby, it is excellent in the external appearance, and the display quality concerning the image displayed on the display surface of the display panel can be enhanced.
(2)前記フレームには、前記機能性板状部材の外周部分及び前記保護板材の前記張出部分が取り付けられている。このようにすれば、フレームには、機能性板状部材の外周部分及び保護板材の張出部分が取り付けられることでそれぞれの保持が図られているので、仮に保護板材をフレーム側とは反対側から押さえる部材を用いて保持を図るようにした場合に比べると、部品点数を削減することができるとともに、外観上も優れる。 (2) The outer peripheral portion of the functional plate member and the protruding portion of the protective plate material are attached to the frame. In this way, the outer peripheral portion of the functional plate member and the overhanging portion of the protective plate material are attached to the frame so that the respective holding is achieved. The number of parts can be reduced and the appearance is excellent as compared with the case where the holding is performed using a member pressed from the outside.
(3)前記機能性板状部材の外周部分と前記フレームとを固着する第1固着部材と、前記保護板材の前記張出部分と前記フレームとを固着する第2固着部材とが備えられており、前記挿通孔は、前記フレームにおいて前記第1固着部材と前記第2固着部材との間に位置して配されている。このようにすれば、第1固着部材及び第2固着部材によって機能性板状部材及び保護板材がフレームに対して固着されて安定的な保持が図られる。挿通孔は、フレームにおいて第1固着部材と第2固着部材との間に位置して配されることで、機能性板状部材及び保護板材の固着を妨げることなく、接続部材の挿通を図ることができる。 (3) A first fixing member for fixing the outer peripheral portion of the functional plate member and the frame, and a second fixing member for fixing the protruding portion of the protective plate material and the frame are provided. The insertion hole is disposed between the first fixing member and the second fixing member in the frame. If it does in this way, a functional plate-shaped member and a protection board material will adhere to a frame with the 1st adhering member and the 2nd adhering member, and stable maintenance will be attained. By inserting the insertion hole between the first fixing member and the second fixing member in the frame, the connection member can be inserted without preventing the functional plate member and the protective plate material from being fixed. Can do.
(4)前記フレームは、少なくとも一部が外部に露出することで当該表示装置の外観を構成している。このようにすれば、フレームが当該表示装置の外観を構成しているので、仮に接続部材をフレームの外側に回り込ませた場合には、接続部材が外部に露出することになるものの、挿通孔によって接続部材を当該表示装置の内部に配置することができ、外観に優れる。また、仮に接続部材をフレームの外側に回り込ませたとき、接続部材を覆う部材を追加することが考えられるが、それに比べると、部品点数が少なく済むとともに全体を小型に保つことができる。 (4) At least a part of the frame is exposed to the outside so as to configure the appearance of the display device. In this way, since the frame constitutes the appearance of the display device, if the connecting member is turned around to the outside of the frame, the connecting member will be exposed to the outside, but the insertion hole The connecting member can be disposed inside the display device, and the appearance is excellent. In addition, when the connecting member is turned to the outside of the frame, it is conceivable to add a member that covers the connecting member. However, compared with that, the number of parts can be reduced and the whole can be kept small.
(5)前記表示パネルに対して前記表示面側とは反対側に配されるとともに、前記表示パネルに光を供給する照明装置が備えられており、前記照明装置は、光源と、前記表示パネルに対して前記表示面側とは反対側に重なる形で配されるとともに、端面が前記光源と対向状をなし、板面から前記表示パネルへ向けて光を出射させる導光板と、前記フレームとの間で前記表示パネル及び前記導光板を挟み込む形で保持し且つ前記光源を収容するシャーシとを有している。このようにすれば、光源からの光が導光板の端面に入射されると、導光板内を伝播されてから表示パネルへ向けて出射される。表示パネルでは、照明装置から供給された光を利用して表示面に画像が表示される。機能性板状部材と表示パネルとの間に介在するフレームによって、表示パネル及び導光板をシャーシとの間で挟み込む形で保持することができる。これにより、仮に導光板と表示パネルとの間に枠状の部材を介在させた場合に比べると、当該表示装置の薄型化を図ることができるとともに、部品点数の削減を図ることができる。 (5) An illuminating device that is disposed on a side opposite to the display surface side with respect to the display panel and that supplies light to the display panel is provided. The illuminating device includes a light source, the display panel And a light guide plate that is arranged on the opposite side to the display surface side, has an end surface facing the light source, and emits light from the plate surface toward the display panel, and the frame. And a chassis for holding the light source and holding the display panel and the light guide plate therebetween. In this way, when light from the light source is incident on the end face of the light guide plate, it is propagated through the light guide plate and then emitted toward the display panel. In the display panel, an image is displayed on the display surface using light supplied from the lighting device. The display panel and the light guide plate can be held between the functional plate member and the display panel so as to be sandwiched between the chassis and the chassis. Thereby, as compared with a case where a frame-like member is interposed between the light guide plate and the display panel, the display device can be reduced in thickness and the number of components can be reduced.
(6)前記照明装置には、前記光源が設けられる光源基板が備えられており、前記シャーシの一部は、前記導光板の端面と対向状をなす対向面を有し、その対向面に前記光源基板が取り付けられてなる基板取付部とされている。このようにすれば、表示パネル及び導光板は、互いに重なる形で配された状態でシャーシとフレームとの間に挟み込まれる形で保持されており、導光板と表示パネルとの間に枠状の部材が介在する構成となっていないから、シャーシ及びフレームの保持力によっては導光板が板厚方向について位置ずれするおそれがある。その点、上記したようにシャーシの一部は、導光板の端面と対向状をなす対向面を有し、その対向面に光源基板が取り付けられる基板取付部とされているから、仮に光源基板をシャーシとは別の部材に取り付け、その部材を基板取付部に取り付けるようにした場合に比べると、光源基板と基板取付部との間に生じ得る組み付け誤差を小さくすることができる。それに加えて、光源基板を基板取付部における導光板の端面との対向面に直接取り付けることで、光源を導光板の端面に対して対向状に配置しつつ同端面に沿う方向について容易に位置合わせすることができる。これにより、導光板の端面に沿う方向について同端面と光源との間に生じ得る位置ずれを低減させることができる。従って、光源から導光板の端面に入射される光の入射効率を向上させることができるとともに、導光板の板面からの出射光に輝度ムラが生じ難くなる。 (6) The illumination device includes a light source substrate on which the light source is provided, and a part of the chassis has a facing surface that is opposed to the end surface of the light guide plate, It is set as the board | substrate attaching part by which a light source board | substrate is attached. In this way, the display panel and the light guide plate are held in a state of being sandwiched between the chassis and the frame in a state of being overlapped with each other, and a frame-like shape is provided between the light guide plate and the display panel. Since the members are not interposed, the light guide plate may be displaced in the thickness direction depending on the holding force of the chassis and the frame. In that respect, as described above, a part of the chassis has a facing surface that is opposed to the end surface of the light guide plate, and is a substrate mounting portion on which the light source substrate is mounted. As compared with the case where the member is attached to a member different from the chassis and the member is attached to the board attaching portion, an assembling error that can occur between the light source board and the substrate attaching portion can be reduced. In addition, by directly attaching the light source substrate to the surface facing the end surface of the light guide plate in the substrate mounting portion, the light source is arranged in a confronting manner with respect to the end surface of the light guide plate and easily aligned in the direction along the end surface. can do. Thereby, the position shift which may arise between the end surface and a light source about the direction along the end surface of a light-guide plate can be reduced. Accordingly, it is possible to improve the incident efficiency of light incident on the end surface of the light guide plate from the light source, and it is difficult for unevenness in luminance to occur in the light emitted from the plate surface of the light guide plate.
(7)前記シャーシは、前記導光板を前記表示パネル側とは反対側から支持する導光板支持部と、前記導光板支持部よりも前記導光板側とは反対側に膨出する形で設けられるとともに、前記基板取付部に取り付けられている前記光源基板を収容し且つ前記基板取付部に連なる基板収容部とを有しているのに対し、前記基板収容部における外面に接する形で取り付けられる放熱部材が備えられている。このようにすれば、導光板支持部よりも導光板側とは反対側に膨出する基板収容部によって基板取付部に取り付けられる光源基板の収容スペースを十分に確保することができる。これにより、光源基板に設けられる光源における導光板の板厚方向についての寸法に関する設計上の自由度を高めることができるから、光源から導光板の端面に入射する光の入射効率を最適化する上で有用となる。しかも、光源が発光するのに伴って生じる熱は、光源基板及び基板取付部から基板収容部へと伝達されてから、導光板支持部へと伝達されるとともに基板収容部の外面に接する形で取り付けられる放熱部材へと伝達される。上記したように光源基板は、基板取付部に対して直接取り付けられているため、仮に放熱部材を介して基板取付部に取り付けられたものに比べると、光源からの熱が放熱され難くなっている。その点、上記したように基板収容部の外面に接する形で放熱部材を取り付けるようにすれば、光源基板と基板取付部との間に生じ得る組み付け誤差を小さくしつつも、放熱性能を十分に補うことができる。 (7) The chassis is provided with a light guide plate support portion that supports the light guide plate from the side opposite to the display panel side, and a shape that bulges to the opposite side of the light guide plate side from the light guide plate support portion. In addition, the light source substrate mounted on the substrate mounting portion is accommodated and connected to the substrate mounting portion, while being attached in contact with the outer surface of the substrate housing portion. A heat radiating member is provided. If it does in this way, the accommodation space of the light source substrate attached to a substrate attachment part can be fully secured by the substrate accommodation part which swells to the opposite side to the light guide plate side rather than the light guide plate support part. As a result, it is possible to increase the degree of design freedom regarding the dimension of the light guide plate in the thickness direction of the light source provided on the light source substrate. It will be useful in. In addition, heat generated as the light source emits light is transmitted from the light source substrate and the substrate mounting portion to the substrate housing portion, and then transmitted to the light guide plate support portion and in contact with the outer surface of the substrate housing portion. It is transmitted to the heat radiating member to be attached. As described above, since the light source substrate is directly attached to the substrate attachment portion, heat from the light source is less likely to be dissipated than a case where the light source substrate is attached to the substrate attachment portion via a heat dissipation member. . In that respect, if the heat radiating member is attached so as to be in contact with the outer surface of the substrate housing portion as described above, sufficient heat radiation performance can be achieved while reducing the assembly error that may occur between the light source substrate and the substrate attachment portion. Can be supplemented.
(8)前記放熱部材は、前記基板収容部の外面に並行し且つ同外面に接する第1放熱部と、前記第1放熱部に連なるとともに前記基板取付部に並行する第2放熱部とを有しており、前記フレームは、前記表示パネルを前記導光板側とは反対側から押さえるフレーム基部と、前記フレーム基部から前記第2放熱部に沿って突出するとともに前記第2放熱部に接する形で取り付けられる取付板部とを有しており、さらには前記挿通孔は、前記基板取付部と前記取付板部との間に位置して配されているのに対し、前記放熱部材には、前記挿通孔に連通することで前記接続部材を通す連通切欠部が形成されている。このようにすれば、基板収容部からの熱は、放熱部材における第1放熱部から第2放熱部へと伝達された後、第2放熱部に接する形で取り付けられるフレームの取付板部へと伝達される。これにより、フレームを利用して光源の放熱を図ることができるから、放熱性能に一層優れる。しかも、シャーシの基板収容部とフレームの取付板部とに取り付けられる放熱部材には、取付板部と基板取付部との間に位置して配される挿通孔に連通する連通切欠部が形成されているから、接続部材を挿通孔及び連通切欠部に通して制御部材に接続することができる。 (8) The heat dissipating member includes a first heat dissipating part that is parallel to and in contact with the outer surface of the substrate housing part, and a second heat dissipating part that is connected to the first heat dissipating part and is parallel to the substrate mounting part. The frame has a frame base that holds the display panel from the side opposite to the light guide plate, a frame that protrudes from the frame base along the second heat radiating portion, and is in contact with the second heat radiating portion. An attachment plate portion to be attached, and the insertion hole is disposed between the substrate attachment portion and the attachment plate portion. A communication cutout portion through which the connection member passes is formed by communicating with the insertion hole. In this way, the heat from the substrate housing portion is transferred from the first heat radiating portion to the second heat radiating portion in the heat radiating member, and then to the mounting plate portion of the frame that is attached in contact with the second heat radiating portion. Communicated. Thereby, since the heat radiation of the light source can be achieved using the frame, the heat radiation performance is further improved. In addition, the heat radiating member attached to the board housing part of the chassis and the mounting plate part of the frame is formed with a communication notch that communicates with an insertion hole located between the mounting plate part and the board mounting part. Therefore, the connecting member can be connected to the control member through the insertion hole and the communication notch.
(9)前記放熱部材の前記第2放熱部と前記基板取付部との間には、隙間が有されており、前記挿通孔は、前記隙間に臨む位置に配されている。このようにすれば、挿通孔に通された接続部材は、放熱部材の連通切欠部に加えて、第2放熱部と基板取付部との間に有される隙間に通されることで、制御部材へとより容易に引き回される。 (9) A gap is provided between the second heat radiating portion of the heat radiating member and the board mounting portion, and the insertion hole is disposed at a position facing the gap. In this way, the connection member passed through the insertion hole is controlled by being passed through the gap between the second heat radiating portion and the board mounting portion in addition to the communication notch portion of the heat radiating member. It is more easily routed to the member.
(10)前記フレームにおける前記挿通孔の孔縁には、テーパ面が形成されている。このようにすれば、接続部材を挿通孔に通す際に、挿通孔の孔縁によって接続部材が損傷を受ける事態が生じ難くなる。 (10) A tapered surface is formed at a hole edge of the insertion hole in the frame. If it does in this way, when passing a connection member through an insertion hole, it will become difficult to produce the situation where a connection member is damaged by the hole edge of an insertion hole.
(11)前記表示パネルは、一対の基板間に液晶を封入してなる液晶パネルとされる。このような表示装置は液晶表示装置として、種々の用途、例えばタブレット型パソコンや携帯型情報端末のディスプレイ等に好適に適用できる。 (11) The display panel is a liquid crystal panel in which liquid crystal is sealed between a pair of substrates. Such a display device can be suitably applied as a liquid crystal display device to various uses such as a display of a tablet personal computer or a portable information terminal.

 まず、液晶表示ユニットLDUを構成する液晶パネル11について詳しく説明する。液晶パネル11は、図3及び図4に示すように、横長な方形状をなすとともにほぼ透明で優れた透光性を有するガラス製の一対の基板11a,11bと、両基板11a,11b間に介在し、電界印加に伴って光学特性が変化する物質である液晶分子を含む液晶層(図示せず)とを備え、両基板11a,11bが液晶層の厚さ分のギャップを維持した状態で図示しないシール剤によって貼り合わせられている。この液晶パネル11は、画像が表示される表示領域(後述する板面遮光層41により囲まれた中央部分)と、表示領域を取り囲む額縁状をなすとともに画像が表示されない非表示領域(後述する板面遮光層41と重畳する外周部分)とを有している。なお、液晶パネル11における長辺方向がX軸方向と一致し、短辺方向がY軸方向と一致し、さらに厚さ方向がZ軸方向と一致している。 First, the liquid crystal panel 11 constituting the liquid crystal display unit LDU will be described in detail. As shown in FIG. 3 and FIG. 4, the liquid crystal panel 11 has a horizontally long rectangular shape and is substantially transparent and has a light-transmitting pair of substrates 11a and 11b, and between the substrates 11a and 11b. And a liquid crystal layer (not shown) including liquid crystal molecules that are substances whose optical characteristics change with application of an electric field, and the substrates 11a and 11b maintain a gap corresponding to the thickness of the liquid crystal layer. It is bonded together with a sealing agent (not shown). The liquid crystal panel 11 has a display area (a central part surrounded by a plate-side light shielding layer 41 described later) and a non-display area (a board described later) that forms a frame surrounding the display area and does not display an image. And an outer peripheral portion overlapping with the surface light shielding layer 41. The long side direction in the liquid crystal panel 11 coincides with the X-axis direction, the short side direction coincides with the Y-axis direction, and the thickness direction coincides with the Z-axis direction.
 両基板11a,11bのうち表側(正面側)がCF基板11aとされ、裏側(背面側)がアレイ基板11bとされる。アレイ基板11bにおける内面側(液晶層側、CF基板11aとの対向面側)には、スイッチング素子であるTFT(Thin Film Transistor)及び画素電極が多数個並んで設けられるとともに、これらTFT及び画素電極の周りには、格子状をなすゲート配線及びソース配線が取り囲むようにして配設されている。各配線には、図示しない制御回路から所定の画像信号が供給されるようになっている。画素電極は、ITO(Indium Tin Oxide:酸化インジウム錫)或いはZnO(Zinc Oxide:酸化亜鉛)といった透明電極からなる。 Among the substrates 11a and 11b, the front side (front side) is the CF substrate 11a, and the back side (back side) is the array substrate 11b. On the inner surface side (the liquid crystal layer side, the surface facing the CF substrate 11a) of the array substrate 11b, a number of TFTs (Thin Film Transistors) and pixel electrodes, which are switching elements, are provided side by side. A gate wiring and a source wiring having a lattice shape are arranged around the gate. A predetermined image signal is supplied to each wiring from a control circuit (not shown). The pixel electrode is made of a transparent electrode such as ITO (Indium Tin Oxide) or ZnO (Zinc Oxide).
 一方、CF基板11aには、各画素に対応した位置に多数個のカラーフィルタが並んで設けられている。カラーフィルタは、R,G,Bの三色が交互に並ぶ配置とされる。各カラーフィルタ間には、混色を防ぐための遮光層(ブラックマトリクス)が形成されている。カラーフィルタ及び遮光層の表面には、アレイ基板11b側の画素電極と対向する対向電極が設けられている。このCF基板11aは、アレイ基板11bよりも一回り小さい大きさとされる。また、両基板11a,11bの内面側には、液晶層に含まれる液晶分子を配向させるための配向膜がそれぞれ形成されている。なお、両基板11a,11bの外面側には、それぞれ偏光板11c,11dが貼り付けられている(図5から図8を参照)。 On the other hand, on the CF substrate 11a, a large number of color filters are arranged side by side at positions corresponding to the respective pixels. The color filter is arranged so that three colors of R, G, and B are alternately arranged. A light shielding layer (black matrix) for preventing color mixture is formed between the color filters. On the surface of the color filter and the light shielding layer, a counter electrode facing the pixel electrode on the array substrate 11b side is provided. The CF substrate 11a is slightly smaller than the array substrate 11b. An alignment film for aligning liquid crystal molecules contained in the liquid crystal layer is formed on the inner surfaces of both the substrates 11a and 11b. Note that polarizing plates 11c and 11d are attached to the outer surfaces of both the substrates 11a and 11b, respectively (see FIGS. 5 to 8).
 続いて、液晶表示ユニットLDUを構成するバックライト装置12について詳しく説明する。バックライト装置12は、図1に示すように、全体として液晶パネル11と同様に横長の略ブロック状をなしている。バックライト装置12は、図3及び図4に示すように、光源であるLED(Light Emitting Diode:発光ダイオード)17と、LED17が実装されたLED基板(光源基板)18と、LED17からの光を導光する導光板19と、導光板19上に積層配置される光学シート(光学部材)20と、導光板19を表側から押さえる遮光フレーム21と、LED基板18、導光板19、光学シート20及び遮光フレーム21を収容するシャーシ22と、シャーシ22の外面に接する形で取り付けられる放熱部材23とを備える。このバックライト装置12は、その外周部分のうち長辺側の一端部にLED17(LED基板18)が偏在する形で配された、いわゆるエッジライト型(サイドライト型)とされる。 Subsequently, the backlight device 12 constituting the liquid crystal display unit LDU will be described in detail. As shown in FIG. 1, the backlight device 12 has a horizontally long and substantially block shape as in the liquid crystal panel 11 as a whole. As shown in FIGS. 3 and 4, the backlight device 12 includes an LED (LightLEDEmitting Diode) 17 that is a light source, an LED substrate (light source substrate) 18 on which the LED 17 is mounted, and light from the LED 17. A light guide plate 19 that guides light, an optical sheet (optical member) 20 that is laminated on the light guide plate 19, a light shielding frame 21 that holds the light guide plate 19 from the front side, an LED substrate 18, a light guide plate 19, an optical sheet 20, and A chassis 22 that houses the light shielding frame 21 and a heat dissipation member 23 that is attached in contact with the outer surface of the chassis 22 are provided. The backlight device 12 is of a so-called edge light type (side light type) in which LEDs 17 (LED substrates 18) are unevenly distributed at one end portion on the long side of the outer peripheral portion.
 LED17は、図3及び図5に示すように、LED基板18に固着される基板部上にLEDチップを樹脂材により封止した構成とされる。基板部に実装されるLEDチップは、主発光波長が1種類とされ、具体的には、青色を単色発光するものが用いられている。その一方、LEDチップを封止する樹脂材には、LEDチップから発せられた青色の光により励起されて所定の色を発光する蛍光体が分散配合されており、全体として概ね白色光を発するものとされる。なお、蛍光体としては、例えば黄色光を発光する黄色蛍光体、緑色光を発光する緑色蛍光体、及び赤色光を発光する赤色蛍光体の中から適宜組み合わせて用いたり、またはいずれか1つを単独で用いることができる。このLED17は、LED基板18に対する実装面とは反対側の面が発光面17aとなる、いわゆる頂面発光型とされている。 3 and 5, the LED 17 has a configuration in which an LED chip is sealed with a resin material on a substrate portion fixed to the LED substrate 18. The LED chip mounted on the substrate unit has one main emission wavelength, and specifically, one that emits blue light in a single color is used. On the other hand, the resin material that seals the LED chip is dispersed and blended with a phosphor that emits a predetermined color when excited by the blue light emitted from the LED chip, and generally emits white light as a whole. It is said. In addition, as the phosphor, for example, a yellow phosphor that emits yellow light, a green phosphor that emits green light, and a red phosphor that emits red light are used in appropriate combination, or any one of them is used. It can be used alone. The LED 17 is a so-called top surface light emitting type in which a surface opposite to the mounting surface with respect to the LED substrate 18 is a light emitting surface 17a.
 LED基板18は、図3及び図5に示すように、X軸方向(導光板19及びシャーシ22の長辺方向)に沿って延在する、長手の板状をなしており、その板面をX軸方向及びZ軸方向に並行させた姿勢、すなわち液晶パネル11及び導光板19の板面と直交させた姿勢でシャーシ22内に収容されている。つまり、このLED基板18は、板面における長辺方向がX軸方向と、短辺方向がZ軸方向とそれぞれ一致し、さらには板面と直交する板厚方向がY軸方向と一致した姿勢とされる。LED基板18は、その内側を向いた板面(実装面18a)が導光板19における一方の長辺側の端面(光入射面19b)に対してY軸方向について所定の間隔を空けつつ対向状に配されている。従って、LED17及びLED基板18と導光板19との並び方向は、Y軸方向とほぼ一致している。このLED基板18は、その長さ寸法が導光板19の長辺寸法とほぼ同じ程度とされており、後述するシャーシ22における長辺側の一端部に取り付けられている。 As shown in FIGS. 3 and 5, the LED substrate 18 has a long plate shape extending along the X-axis direction (the long side direction of the light guide plate 19 and the chassis 22). The chassis 22 is accommodated in a posture parallel to the X-axis direction and the Z-axis direction, that is, a posture orthogonal to the plate surfaces of the liquid crystal panel 11 and the light guide plate 19. That is, the LED substrate 18 has a posture in which the long side direction on the plate surface coincides with the X-axis direction, the short side direction coincides with the Z-axis direction, and the plate thickness direction orthogonal to the plate surface coincides with the Y-axis direction. It is said. The LED substrate 18 is opposed to the inner surface of the light guide plate 19 (mounting surface 18a) with a predetermined interval in the Y-axis direction with respect to the end surface (light incident surface 19b) on one long side of the light guide plate 19. It is arranged in. Therefore, the alignment direction of the LED 17 and the LED substrate 18 and the light guide plate 19 substantially coincides with the Y-axis direction. The LED board 18 has a length dimension substantially the same as the long side dimension of the light guide plate 19 and is attached to one end portion of the long side of the chassis 22 described later.
 LED基板18のうち内側、つまり導光板19側を向いた板面(導光板19との対向面)には、図5に示すように、上記した構成のLED17が表面実装されており、ここが実装面18aとされる。LED17は、LED基板18の実装面18aにおいて、その長さ方向(X軸方向)に沿って複数が所定の間隔を空けつつ一列に(直線的に)並列配置されている。つまり、LED17は、バックライト装置12における長辺側の一端部において長辺方向に沿って複数ずつ間欠的に並列配置されていると言える。また、LED基板18の実装面18aには、X軸方向に沿って延在するとともにLED17群を横切って隣り合うLED17同士を直列接続する、金属膜(銅箔など)からなる配線パターン(図示せず)が形成されており、この配線パターンの両端部に形成された端子部が外部のLED駆動回路に接続されることで、駆動電力を各LED17に供給することが可能とされる。また、LED基板18の基材は、シャーシ22と同様に金属製とされ、その表面に絶縁層を介して既述した配線パターン(図示せず)が形成されている。なお、LED基板18の基材に用いる材料としては、セラミックなどの絶縁材料を用いることも可能である。 On the inner side of the LED substrate 18, that is, the plate surface facing the light guide plate 19 (the surface facing the light guide plate 19), as shown in FIG. The mounting surface 18a is used. A plurality of LEDs 17 are arranged in a line (linearly) in parallel on the mounting surface 18a of the LED substrate 18 along the length direction (X-axis direction) with a predetermined interval. That is, it can be said that a plurality of LEDs 17 are intermittently arranged in parallel along the long side direction at one end portion on the long side of the backlight device 12. A wiring pattern (not shown) made of a metal film (such as copper foil) is provided on the mounting surface 18a of the LED substrate 18 and extends in the X-axis direction and connects adjacent LEDs 17 in series across the LED 17 group. And the terminal portions formed at both ends of the wiring pattern are connected to an external LED driving circuit, so that driving power can be supplied to each LED 17. Further, the base material of the LED substrate 18 is made of metal like the chassis 22, and the wiring pattern (not shown) described above is formed on the surface thereof via an insulating layer. In addition, as a material used for the base material of LED board 18, insulating materials, such as a ceramic, can also be used.
 導光板19は、図3及び図4に示すように、屈折率が空気よりも十分に高く且つほぼ透明な(透光性に優れた)合成樹脂材料(例えばアクリルなど)からなる。導光板19は、液晶パネル11と同様に平面に視て横長の方形状をなす平板状とされており、その板面が液晶パネル11の板面(表示面DS)に並行している。導光板19は、その板面における長辺方向がX軸方向と、短辺方向がY軸方向とそれぞれ一致し、且つ板面と直交する板厚方向がZ軸方向と一致している。導光板19は、シャーシ22内において液晶パネル11及び光学シート20の直下位置に配されており、その外周端面のうちの一方の長辺側の端面がシャーシ22における長辺側の一端部に配されたLED基板18の各LED17とそれぞれ対向状をなしている。従って、LED17(LED基板18)と導光板19との並び方向がY軸方向と一致するのに対して、光学シート20(液晶パネル11)と導光板19との並び方向(重なり方向)がZ軸方向と一致しており、両並び方向が互いに直交するものとされる。そして、導光板19は、LED17からY軸方向に沿って発せられた光を長辺側の端面から導入するとともに、その光を内部で伝播させつつ光学シート20側(表側、光出射側)へ向くよう立ち上げて板面から出射させる機能を有する。 As shown in FIGS. 3 and 4, the light guide plate 19 is made of a synthetic resin material (for example, acrylic) having a refractive index sufficiently higher than that of air and substantially transparent (excellent translucency). The light guide plate 19 is in the form of a flat plate that is horizontally long when viewed in a plane, like the liquid crystal panel 11, and the plate surface is parallel to the plate surface (display surface DS) of the liquid crystal panel 11. The light guide plate 19 has a long side direction on the plate surface corresponding to the X-axis direction, a short side direction corresponding to the Y-axis direction, and a plate thickness direction orthogonal to the plate surface corresponding to the Z-axis direction. The light guide plate 19 is disposed immediately below the liquid crystal panel 11 and the optical sheet 20 in the chassis 22, and one of the outer peripheral end surfaces of the light guide plate 19 is disposed at one end of the chassis 22 on the long side. Each LED 17 on the LED board 18 is opposed to each other. Therefore, while the alignment direction of the LED 17 (LED substrate 18) and the light guide plate 19 coincides with the Y-axis direction, the alignment direction (overlapping direction) of the optical sheet 20 (liquid crystal panel 11) and the light guide plate 19 is Z. It is coincident with the axial direction, and both alignment directions are orthogonal to each other. The light guide plate 19 introduces light emitted from the LED 17 along the Y-axis direction from the end surface on the long side, and propagates the light inside to the optical sheet 20 side (front side, light emission side). It has the function of rising up and emitting from the plate surface.
 平板状をなす導光板19の板面のうち、表側を向いた面(液晶パネル11や光学シート20との対向面)は、図3及び図4に示すように、内部の光を光学シート20及び液晶パネル11側に向けて出射させる光出射面19aとなっている。導光板19における板面に対して隣り合う外周端面のうち、X軸方向(LED17の並び方向、LED基板18の長辺方向)に沿って長手状をなす一対の長辺側の端面のうちの一方(図3に示す左側)の端面は、図5に示すように、LED17(LED基板18)と所定の空間を空けて対向状をなしており、これがLED17から発せられた光が入射される光入射面19bとなっている。光入射面19bは、X軸方向及びZ軸方向に沿って並行する面とされ、光出射面19aに対して略直交する面とされる。また、LED17と光入射面19b(導光板19)との並び方向は、Y軸方向と一致しており、光出射面19aに並行している。なお、導光板19の外周端面のうち、光入射面19bとは反対側の長辺側の端面及び短辺側の一対の端面は、図4及び図6に示すように、それぞれLED17とは対向しないLED非対向端面とされる。 Among the plate surfaces of the light guide plate 19 having a flat plate shape, the surface facing the front side (the surface facing the liquid crystal panel 11 and the optical sheet 20) transmits the internal light to the optical sheet 20 as shown in FIGS. In addition, a light emission surface 19a that emits light toward the liquid crystal panel 11 is formed. Of the outer peripheral end faces adjacent to the plate surface of the light guide plate 19, of the pair of long side end faces that form a longitudinal shape along the X-axis direction (LED 17 alignment direction, LED board 18 long side direction) As shown in FIG. 5, one end face (left side shown in FIG. 3) is opposed to the LED 17 (LED substrate 18) with a predetermined space therebetween, and light emitted from the LED 17 is incident thereon. It is a light incident surface 19b. The light incident surface 19b is a surface that is parallel to the X-axis direction and the Z-axis direction, and is a surface that is substantially orthogonal to the light emitting surface 19a. Further, the alignment direction of the LED 17 and the light incident surface 19b (light guide plate 19) coincides with the Y-axis direction and is parallel to the light emitting surface 19a. Of the outer peripheral end surface of the light guide plate 19, the long side end surface and the pair of short side end surfaces opposite to the light incident surface 19b are opposed to the LED 17, respectively, as shown in FIGS. The LED non-opposing end face is not used.
 導光板19の板面のうち、光出射面19aとは反対側の板面19cには、図3及び図4に示すように、導光板19内の光を反射して表側へ立ち上げることが可能な反射シートRがその全域を覆う形で設けられている。言い換えると、反射シートRは、シャーシ22の底板22aと導光板19との間に挟まれた形で配されている。この反射シートRのうち、導光板19における光入射面19b側の端部は、図5に示すように、光入射面19bよりも外側、つまりLED17側に向けて延出されており、この延出部分によってLED17からの光を反射することで、光入射面19bへの光の入射効率を向上させることができる。なお、導光板19における光出射面19aと反対側の板面19cとの少なくともいずれか一方、または反射シートRの表面には、導光板19内の光を散乱させる散乱部(図示せず)などが所定の面内分布を持つようパターニングされており、それにより光出射面19aからの出射光が面内において均一な分布となるよう制御されている。 Of the plate surfaces of the light guide plate 19, the plate surface 19c opposite to the light exit surface 19a can reflect the light in the light guide plate 19 and rise to the front side as shown in FIGS. A possible reflection sheet R is provided so as to cover the entire area. In other words, the reflection sheet R is disposed between the bottom plate 22 a of the chassis 22 and the light guide plate 19. In the reflection sheet R, the end of the light guide plate 19 on the light incident surface 19b side is extended to the outside of the light incident surface 19b, that is, toward the LED 17, as shown in FIG. By reflecting the light from the LED 17 by the exit portion, the light incident efficiency on the light incident surface 19b can be improved. Note that a scattering portion (not shown) that scatters the light in the light guide plate 19 is provided on at least one of the light exit surface 19a and the opposite plate surface 19c of the light guide plate 19 or on the surface of the reflection sheet R. Are patterned so as to have a predetermined in-plane distribution, whereby the light emitted from the light exit surface 19a is controlled to have a uniform distribution in the plane.
 光学シート20は、図3及び図4に示すように、液晶パネル11及びシャーシ22と同様に平面に視て横長の方形状をなしている。光学シート20は、導光板19の光出射面19a上に載せられていて液晶パネル11と導光板19との間に介在して配されることで、導光板19からの出射光を透過するとともにその透過光に所定の光学作用を付与しつつ液晶パネル11に向けて出射させる。光学シート20は、互いに積層される複数枚(本実施形態では3枚)のシート状の部材からなるものとされる。具体的な光学シート20の種類としては、例えば拡散シート、レンズシート、反射型偏光シートなどがあり、これらの中から適宜に選択して使用することが可能である。 As shown in FIGS. 3 and 4, the optical sheet 20 has a horizontally long rectangular shape when viewed in a plane, like the liquid crystal panel 11 and the chassis 22. The optical sheet 20 is placed on the light output surface 19 a of the light guide plate 19 and is disposed between the liquid crystal panel 11 and the light guide plate 19 so as to transmit the light emitted from the light guide plate 19. The transmitted light is emitted toward the liquid crystal panel 11 while giving a predetermined optical action. The optical sheet 20 is composed of a plurality of (three in the present embodiment) sheet-like members stacked on each other. Specific types of the optical sheet 20 include, for example, a diffusion sheet, a lens sheet, a reflective polarizing sheet, and the like, which can be appropriately selected and used.
 遮光フレーム21は、図3及び図4に示すように、導光板19の外周部分(外周端部)に倣う形で延在する略枠状(額縁状)に形成されており、導光板19の外周部分をほぼ全周にわたって表側から押さえることが可能とされる。この遮光フレーム21は、合成樹脂製とされるとともに、表面が例えば黒色を呈する形態とされることで、遮光性を有するものとされる。遮光フレーム21は、図5から図7に示すように、その内端部21aが導光板19の外周部分及びLED17と、液晶パネル11及び光学シート20の各外周部分(外周端部)との間に全周にわたって介在する形で配されており、これらが光学的に独立するように仕切っている。これにより、LED17から発せられて光入射面19bに入光しない光や導光板19の端面(光入射面19b及びLED17とは対向しない3つのLED非対向端面)から漏れ出した光が、液晶パネル11及び光学シート20の各外周部分(特に端面)に直接入光するのを遮光することができるものとされる。また、遮光フレーム21のうち、LED17及びLED基板18とは平面に視て重畳しない3つの各辺部(一対の短辺部とLED基板18側とは反対側の長辺部)については、シャーシ22の底板22aから立ち上がる部分と、フレーム13を裏側から支持する部分とを有しているのに対し、LED17及びLED基板18と平面に視て重畳する長辺部については、導光板19の端部及びLED基板18(LED17)を表側から覆うとともに一対の短辺部間を架橋する形で形成されている。また、この遮光フレーム21は、次述するシャーシ22に対して図示しないネジ部材などの固定手段によって固定されている。なお、図4に示す右側端部は、図7にて拡大図が示される図4に示す左側端部と左右対称をなしているため、拡大図の図示を省略している。 3 and 4, the light shielding frame 21 is formed in a substantially frame shape (frame shape) extending so as to follow the outer peripheral portion (outer peripheral end portion) of the light guide plate 19. The outer peripheral portion can be pressed from the front side over almost the entire circumference. The light-shielding frame 21 is made of synthetic resin and has a light-shielding property because the surface has a form of black, for example. As shown in FIGS. 5 to 7, the light shielding frame 21 has an inner end portion 21 a between the outer peripheral portion of the light guide plate 19 and the LED 17 and the outer peripheral portions (outer peripheral end portions) of the liquid crystal panel 11 and the optical sheet 20. And are arranged so as to be optically independent. Thereby, the light emitted from the LED 17 and not entering the light incident surface 19b or the light leaking from the end surfaces of the light guide plate 19 (the three LED non-opposing end surfaces not facing the light incident surface 19b and the LED 17) 11 and the optical sheet 20 can be blocked from directly entering the outer peripheral portions (particularly the end faces). In addition, in the light shielding frame 21, three side portions (a pair of short side portions and a long side portion opposite to the LED substrate 18 side) that do not overlap with the LED 17 and the LED substrate 18 in a plan view are chassis. 22 has a portion that rises from the bottom plate 22a and a portion that supports the frame 13 from the back side, but the long side portion that overlaps the LED 17 and the LED substrate 18 in a plan view is the end of the light guide plate 19. And the LED substrate 18 (LED 17) are covered from the front side and are bridged between a pair of short sides. The light shielding frame 21 is fixed to a chassis 22 described below by fixing means such as a screw member (not shown). Note that the right end portion shown in FIG. 4 is symmetrical with the left end portion shown in FIG. 4 where the enlarged view is shown in FIG.
 シャーシ22は、例えばアルミニウム板や電気亜鉛めっき綱板(SECC)などの熱伝導率に優れた金属板からなり、図3及び図4に示すように、液晶パネル11と同様に横長の方形状をなす底板22aと、底板22aにおける各辺(一対の長辺及び一対の短辺)の外端からそれぞれ表側に向けて立ち上がる側板22bとからなる。シャーシ22(底板22a)は、その長辺方向がX軸方向と一致し、短辺方向がY軸方向と一致している。底板22aは、その大部分が導光板19を裏側(光出射面19a側とは反対側)から支持する導光板支持部22a1とされるのに対し、LED基板18側の端部が段付き状に裏側に膨出する基板収容部22a2とされる。この基板収容部22a2は、図5に示すように、断面形状が略L字型をなしており、導光板支持部22a1の端部から屈曲されて裏側に向けて立ち上がる立ち上がり部38と、立ち上がり部38の立ち上がり先端部から屈曲されて導光板支持部22a1側とは反対側に向けて突出する収容底部39とからなる。この立ち上がり部38における導光板支持部22a1の端部からの屈曲位置は、導光板19の光入射面19bよりもLED17側とは反対側(導光板支持部22a1の中央寄り)に位置している。収容底部39における突出先端部からは、長辺側の側板22bが表側に立ち上がるよう屈曲形成されている。そして、この基板収容部22a2に連なる長辺側の側板22bには、LED基板18が取り付けられており、この側板22bが基板取付部37を構成している。基板取付部37は、導光板19の光入射面19bと対向状をなす対向面を有しており、この対向面にLED基板18が取り付けられている。LED基板18は、LED17が実装された実装面18aとは反対側の板面が、基板取付部37における内側の板面に対して両面テープなどの基板固着部材25を介して接する形で固着されている。取り付けられたLED基板18は、基板収容部22a2をなす収容底部39の内側の板面との間に僅かながらも隙間を有している。 The chassis 22 is made of a metal plate having excellent thermal conductivity, such as an aluminum plate or an electrogalvanized steel plate (SECC), and has a horizontally long rectangular shape as in the liquid crystal panel 11 as shown in FIGS. A bottom plate 22a formed, and a side plate 22b rising from the outer ends of the respective sides (a pair of long sides and a pair of short sides) of the bottom plate 22a toward the front side. The chassis 22 (bottom plate 22a) has a long side direction that matches the X-axis direction, and a short side direction that matches the Y-axis direction. Most of the bottom plate 22a is a light guide plate support portion 22a1 that supports the light guide plate 19 from the back side (the side opposite to the light emitting surface 19a side), whereas the end on the LED substrate 18 side is stepped. The substrate accommodating portion 22a2 bulges to the back side. As shown in FIG. 5, the substrate housing portion 22a2 has a substantially L-shaped cross-section, is bent from the end portion of the light guide plate support portion 22a1, and rises toward the back side, and a rising portion. 38 is composed of an accommodation bottom 39 that is bent from the rising tip of 38 and protrudes toward the side opposite to the light guide plate support 22a1 side. The bent position of the rising portion 38 from the end of the light guide plate support portion 22a1 is located on the opposite side of the light incident surface 19b of the light guide plate 19 from the LED 17 side (near the center of the light guide plate support portion 22a1). . A long side plate 22b is bent from the protruding tip of the housing bottom 39 so as to rise to the front side. The LED substrate 18 is attached to the side plate 22b on the long side continuous to the substrate housing portion 22a2, and the side plate 22b constitutes the substrate attachment portion 37. The board mounting portion 37 has a facing surface that faces the light incident surface 19b of the light guide plate 19, and the LED substrate 18 is mounted on the facing surface. The LED substrate 18 is fixed in such a manner that the plate surface opposite to the mounting surface 18a on which the LED 17 is mounted is in contact with the inner plate surface of the substrate mounting portion 37 via a substrate fixing member 25 such as a double-sided tape. ing. The attached LED board 18 has a slight gap between the LED board 18 and the inner plate surface of the housing bottom 39 that forms the board housing 22a2.
 シャーシ22の底板22aにおける裏側(導光板19側とは反対側、外側)の板面には、図1及び図8に示すように、後述するタッチパネル14のタッチパネル機能を実現するための駆動を制御するためのタッチパネル駆動回路基板(制御部材)26が取り付けられている。タッチパネル駆動回路基板26は、タッチパネル14に所定の電位を供給する図示しないタッチパネル駆動回路を有するとともに、同タッチパネル駆動回路をタッチパネル14に対して電気的に接続するためのフレキシブル基板27の端部に導通接触されるコネクタ部26aを有している。フレキシブル基板(接続部材)27は、絶縁性及び可撓性を有する合成樹脂材料からなるフィルム状の基材上に導電路(配線パターン)が形成されてなる。フレキシブル基板27は、図8に示すように、その一端側がタッチパネル14の長辺側の一端部に対して異方性導電膜(図示せず)を介して圧着により電気的に接続されるのに対し、途中が折り返し状に屈曲されつつ他端側が上記したタッチパネル駆動回路基板26のコネクタ部26aに差し込まれて電気的に接続されている。また、シャーシ22の底板22aにおける裏側の板面には、タッチパネル駆動回路基板26以外にも、液晶パネル11の駆動を制御するための液晶パネル駆動回路基板(図示せず)やLED17に駆動電力を供給するLED駆動回路基板(図示せず)などが取り付けられている。なお、液晶パネル駆動回路基板には、液晶パネル11のうちLED基板18側とは反対側の長辺側端部に接続されるとともに、上記したフレキシブル基板27と同様にして折り返し状に屈曲された図示しないドライバ部材(液晶駆動部材)が電気的に接続されている。 As shown in FIGS. 1 and 8, on the back surface of the bottom plate 22a of the chassis 22 (on the opposite side to the light guide plate 19 side, outside), driving for realizing a touch panel function of the touch panel 14 to be described later is controlled. A touch panel drive circuit board (control member) 26 is attached. The touch panel drive circuit board 26 has a touch panel drive circuit (not shown) that supplies a predetermined potential to the touch panel 14 and is electrically connected to an end of a flexible board 27 for electrically connecting the touch panel drive circuit to the touch panel 14. It has a connector part 26a to be contacted. The flexible substrate (connecting member) 27 is formed by forming a conductive path (wiring pattern) on a film-like base material made of a synthetic resin material having insulation and flexibility. As shown in FIG. 8, one end of the flexible substrate 27 is electrically connected to one end of the long side of the touch panel 14 by crimping via an anisotropic conductive film (not shown). On the other hand, the other end side is inserted into the connector portion 26a of the touch panel drive circuit board 26 and is electrically connected while being bent in the middle. In addition to the touch panel drive circuit board 26, the rear panel surface of the bottom plate 22 a of the chassis 22 supplies drive power to a liquid crystal panel drive circuit board (not shown) and the LED 17 for controlling the drive of the liquid crystal panel 11. An LED driving circuit board (not shown) to be supplied is attached. The liquid crystal panel drive circuit board is connected to the end of the long side opposite to the LED board 18 side of the liquid crystal panel 11 and bent in a folded manner in the same manner as the flexible board 27 described above. A driver member (liquid crystal driving member) (not shown) is electrically connected.
 放熱部材23は、アルミニウム板などの熱伝導率に優れた金属板からなり、図1及び図3に示すように、シャーシ22における長辺側の一端部、詳しくはLED基板18を収容する基板収容部22a2に沿って延在する形態とされる。放熱部材23は、図5に示すように、断面形状が略L字型をなしており、基板収容部22a2の外面に並行し且つその外面に接する第1放熱部23aと、基板収容部22a2に連なる基板取付部37(側板22b)の外面に並行する第2放熱部23bとからなる。第1放熱部23aは、X軸方向に沿って延在する細長い平板状をなしており、X軸方向及びY軸方向に並行する表側を向いた板面が、基板収容部22a2における収容底部39の外面のほぼ全長にわたって当接されている。第1放熱部23aは、収容底部39に対してネジ部材SMによってネジ止めされており、ネジ部材SMを挿通するネジ挿通孔23a1を有している。また、収容底部39には、ネジ部材SMが螺合されるネジ孔28が形成されている。これにより、LED17から発せられた熱は、LED基板18、基板取付部37及び基板収容部22a2を介して第1放熱部23aへと伝達されるようになっている。なお、ネジ部材SMは、第1放熱部23aに対してその延在方向に沿って複数が間欠的に並ぶ形で取り付けられている。第2放熱部23bは、X軸方向に沿って延在する細長い平板状をなしており、X軸方向及びZ軸方向に並行する内側を向いた板面が、基板取付部37における外側の板面との間に所定の隙間C1を空けつつ対向状に配されている。 The heat dissipating member 23 is made of a metal plate having excellent thermal conductivity such as an aluminum plate, and as shown in FIGS. 1 and 3, one end of the long side of the chassis 22, specifically, a substrate housing for housing the LED substrate 18. It is set as the form extended along the part 22a2. As shown in FIG. 5, the heat radiating member 23 has a substantially L-shaped cross section, and is parallel to the outer surface of the substrate housing portion 22a2 and in contact with the outer surface, and the substrate housing portion 22a2. It consists of the 2nd thermal radiation part 23b parallel to the outer surface of the board | substrate attachment part 37 (side plate 22b) which continues. The first heat radiating portion 23a has an elongated flat plate shape extending along the X-axis direction, and the plate surface facing the front side parallel to the X-axis direction and the Y-axis direction has a receiving bottom portion 39 in the substrate receiving portion 22a2. It is contact | abutted over the full length of the outer surface of. The first heat radiating portion 23a is screwed to the housing bottom 39 by a screw member SM, and has a screw insertion hole 23a1 through which the screw member SM is inserted. The accommodation bottom 39 is formed with a screw hole 28 into which the screw member SM is screwed. Thereby, the heat generated from the LED 17 is transmitted to the first heat radiating part 23a via the LED board 18, the board attaching part 37, and the board accommodating part 22a2. Note that a plurality of screw members SM are attached to the first heat radiating portion 23a so as to be intermittently arranged along the extending direction. The second heat dissipating part 23b has an elongated flat plate shape extending along the X-axis direction, and a plate surface facing inward in parallel to the X-axis direction and the Z-axis direction is an outer plate in the board mounting part 37. It is arranged in an opposing manner with a predetermined gap C1 between the surface and the surface.
 続いて、液晶表示ユニットLDUを構成するフレーム13について詳しく説明する。フレーム13は、アルミニウムなどの熱伝導率に優れた金属材料からなるものとされており、図1に示すように、全体としては、液晶パネル11、タッチパネル14及びカバーパネル15の各外周部分(外周端部)に倣う形で延在する横長の略枠状(額縁状)をなしている。フレーム13の製造方法としては、例えばプレス加工などが採られている。フレーム13は、図3及び図4に示すように、液晶パネル11の外周部分を表側から押さえるとともに、バックライト装置12を構成するシャーシ22との間で、互いに積層された液晶パネル11、光学シート20及び導光板19を挟み込む形で保持している。その一方で、フレーム13は、共に板状部材であるタッチパネル14及びカバーパネル15の各外周部分を裏側から受けており、液晶パネル11とタッチパネル14との外周部分間に介在する形で配されている。これにより、液晶パネル11とタッチパネル14との間には、所定の隙間C2が確保されるので、例えばカバーパネル15に外力が作用したとき、カバーパネル15に追従してタッチパネル14が液晶パネル11側に撓むよう変形した場合でも、撓んだタッチパネル14が液晶パネル11に干渉し難くなっている。 Subsequently, the frame 13 constituting the liquid crystal display unit LDU will be described in detail. The frame 13 is made of a metal material having excellent thermal conductivity such as aluminum. As shown in FIG. 1, as a whole, each outer peripheral portion (outer periphery) of the liquid crystal panel 11, the touch panel 14 and the cover panel 15 is used. It has a horizontally long substantially frame shape (frame shape) extending in a manner that follows the end portion. As a method for manufacturing the frame 13, for example, press working or the like is employed. As shown in FIGS. 3 and 4, the frame 13 presses the outer peripheral portion of the liquid crystal panel 11 from the front side, and the liquid crystal panel 11 and the optical sheet stacked with each other with the chassis 22 constituting the backlight device 12. 20 and the light guide plate 19 are held in a sandwiched manner. On the other hand, the frame 13 receives the outer peripheral portions of the touch panel 14 and the cover panel 15, both of which are plate-like members, from the back side, and is arranged so as to be interposed between the outer peripheral portions of the liquid crystal panel 11 and the touch panel 14. Yes. As a result, a predetermined gap C2 is secured between the liquid crystal panel 11 and the touch panel 14, so that when the external force is applied to the cover panel 15, for example, the touch panel 14 follows the cover panel 15 and the liquid crystal panel 11 side. Even when it is deformed so as to be bent, it is difficult for the touch panel 14 to be bent to interfere with the liquid crystal panel 11.
 フレーム13は、図9から図11に示すように、液晶パネル11、タッチパネル14及びカバーパネル15の各外周部分に倣う枠状部(フレーム基部、額縁状部)13aと、枠状部13aの外周端部に連なるとともにタッチパネル14、カバーパネル15及びケーシング16をそれぞれ外周側から取り囲む環状部(筒状部)13bと、枠状部13aから裏側に向けて突出してシャーシ22及び放熱部材23に取り付けられる取付板部13cとを有してなる。 As shown in FIGS. 9 to 11, the frame 13 includes a frame-like portion (frame base portion, frame-like portion) 13 a that follows each outer peripheral portion of the liquid crystal panel 11, the touch panel 14, and the cover panel 15, and the outer periphery of the frame-like portion 13 a. Attached to the chassis 22 and the heat radiating member 23 projecting from the frame-shaped part 13a toward the back side, and an annular part (cylindrical part) 13b that continues to the end and surrounds the touch panel 14, the cover panel 15 and the casing 16 from the outer peripheral side. And an attachment plate portion 13c.
 枠状部13aは、図9から図11に示すように、液晶パネル11、タッチパネル14、及びカバーパネル15の各板面に並行する板面を有する略板状をなすとともに、平面に視て横長で略方形の枠状に形成されている。枠状部13aは、図5から図7に示すように、内周部分13a1よりも外周部分13a2の方が相対的に板厚が厚くなっており、両者の境界位置に段差(ギャップ)GPが形成されている。枠状部13aのうち、内周部分13a1が液晶パネル11の外周部分とタッチパネル14の外周部分との間に介在するのに対し、外周部分13a2がカバーパネル15の外周部分を裏側から受けている。このように、枠状部13aは、その表側の板面がほぼ全域にわたってカバーパネル15によって覆われることになるため、表側の板面が殆ど外部に露出することがないものとされる。これにより、フレーム13がLED17からの熱などにより温度上昇していても、液晶表示装置10の使用者がフレーム13における露出部位に直接接触し難くなるので、安全面で優れる。枠状部13aの内周部分13a1における裏側の板面には、液晶パネル11の外周部分を緩衝しつつ表側から押さえるための緩衝材29が固着されているのに対し、内周部分13a1における表側の板面には、タッチパネル14の外周部分を緩衝しつつ固着するための第1固着部材30が固着されている。これら緩衝材29及び第1固着部材30は、内周部分13a1において平面に視て互いに重畳する位置に配されている。一方、枠状部13aの外周部分13a2における表側の板面には、カバーパネル15の外周部分を緩衝しつつ固着するための第2固着部材31が固着されている。これら緩衝材29及び各固着部材30,31は、枠状部13aのうち四隅の角部を除いた各辺部に沿ってそれぞれ延在する形で配されている。また、各固着部材30,31は、例えば基材がクッション性を有する両面テープからなる。 As shown in FIGS. 9 to 11, the frame-shaped portion 13 a has a substantially plate shape having plate surfaces parallel to the plate surfaces of the liquid crystal panel 11, the touch panel 14, and the cover panel 15, and is horizontally long when viewed in a plane. It is formed in a substantially square frame shape. As shown in FIGS. 5 to 7, the frame portion 13a is relatively thicker at the outer peripheral portion 13a2 than at the inner peripheral portion 13a1, and there is a step (gap) GP at the boundary position between the two. Is formed. Of the frame-shaped portion 13a, the inner peripheral portion 13a1 is interposed between the outer peripheral portion of the liquid crystal panel 11 and the outer peripheral portion of the touch panel 14, whereas the outer peripheral portion 13a2 receives the outer peripheral portion of the cover panel 15 from the back side. . Thus, since the front plate surface of the frame-like portion 13a is almost entirely covered by the cover panel 15, the front plate surface is hardly exposed to the outside. Thereby, even if the temperature of the frame 13 is increased due to heat from the LED 17 or the like, it is difficult for the user of the liquid crystal display device 10 to directly contact the exposed portion of the frame 13, which is excellent in terms of safety. On the back surface of the inner peripheral portion 13a1 of the frame-shaped portion 13a, a cushioning material 29 for adhering the outer peripheral portion of the liquid crystal panel 11 and holding it from the front side is fixed, whereas the front side of the inner peripheral portion 13a1 is fixed. A first fixing member 30 for fixing the outer peripheral portion of the touch panel 14 while buffering is fixed to the plate surface. The cushioning material 29 and the first fixing member 30 are disposed at positions overlapping each other in a plan view in the inner peripheral portion 13a1. On the other hand, a second fixing member 31 for fixing the outer peripheral portion of the cover panel 15 while buffering the outer peripheral portion of the cover panel 15 is fixed to the front plate surface of the outer peripheral portion 13a2 of the frame-like portion 13a. The buffer material 29 and the fixing members 30 and 31 are arranged so as to extend along the side portions of the frame-like portion 13a excluding the corner portions at the four corners. Moreover, each fixing member 30 and 31 consists of a double-sided tape in which a base material has cushioning properties, for example.
 枠状部13aのうち、LED基板18と平面に視て重畳する長辺部には、図8から図11に示すように、タッチパネル14とタッチパネル駆動回路基板26とを電気的に中継接続するためのフレキシブル基板27を挿通する挿通孔32が貫通する形で開口形成されている。挿通孔32は、枠状部13aの上記長辺部のうち、Y軸方向について内周部分13a1と外周部分13a2とに跨る範囲に配されており、後述する取付板部13cよりも内側(シャーシ22側)に配されている。挿通孔32は、Y軸方向についてタッチパネル14の外周部分を枠状部13aの内周部分13a1に固着する第1固着部材30と、カバーパネル15の外周部分を枠状部13aの外周部分13a2に固着する第2固着部材31との間に配されている。挿通孔32は、放熱部材23の第2放熱部23bと、シャーシ22における基板取付部37(側板22b)の外側の板面との間に有される隙間C1に連通する位置に配されており、取付板部13cと基板取付部37との間に位置している。さらには、放熱部材23のうち、挿通孔32と平面に視て重畳する部分には、挿通孔32及び上記隙間C1に連通する連通切欠部33が切欠形成されている。連通切欠部33は、放熱部材23のうち、シャーシ22の基板取付部37よりも外側に配される部分、具体的にはY軸方向について第1放熱部23aにおける第2放熱部23b側の端部(屈曲部付近)から第2放熱部23bの全域にわたる範囲に形成されている。これにより、一端側がタッチパネル14の端部に接続されたフレキシブル基板27の他端側を、挿通孔32、隙間C1、及び連通切欠部33に通すことで、シャーシ22の裏側に配されたタッチパネル駆動回路基板26へと容易に接続することが可能とされる。また、挿通孔32は、枠状部13aの上記長辺部のうち、X軸方向について一方の端部(図10に示す右側、図11に示す左側)寄りに片寄った位置に配されており、その開口幅がフレキシブル基板27の幅寸法より少し広い程度とされる。 As shown in FIGS. 8 to 11, the touch panel 14 and the touch panel drive circuit board 26 are electrically connected to the long side portion of the frame-like portion 13 a that overlaps the LED substrate 18 in a plan view. An opening 32 is formed so as to penetrate through the flexible substrate 27. The insertion hole 32 is arranged in a range straddling the inner peripheral portion 13a1 and the outer peripheral portion 13a2 in the Y-axis direction among the long side portions of the frame-shaped portion 13a, and is located on the inner side (chassis) of the mounting plate portion 13c described later. 22 side). The insertion hole 32 includes a first fixing member 30 that fixes the outer peripheral portion of the touch panel 14 to the inner peripheral portion 13a1 of the frame-shaped portion 13a in the Y-axis direction, and the outer peripheral portion of the cover panel 15 to the outer peripheral portion 13a2 of the frame-shaped portion 13a. It is arranged between the second fixing member 31 to be fixed. The insertion hole 32 is arranged at a position communicating with a gap C <b> 1 provided between the second heat radiating portion 23 b of the heat radiating member 23 and the outer plate surface of the board mounting portion 37 (side plate 22 b) in the chassis 22. , Between the mounting plate portion 13c and the substrate mounting portion 37. Furthermore, a communication notch 33 communicating with the insertion hole 32 and the gap C <b> 1 is formed in the heat radiating member 23 at a portion overlapping the insertion hole 32 in plan view. The communication notch 33 is a portion of the heat dissipation member 23 that is disposed outside the board mounting portion 37 of the chassis 22, specifically, an end on the second heat dissipation portion 23 b side in the first heat dissipation portion 23 a in the Y-axis direction. It is formed in a range extending from the portion (near the bent portion) to the entire area of the second heat radiating portion 23b. Thereby, the other end side of the flexible substrate 27 whose one end side is connected to the end portion of the touch panel 14 is passed through the insertion hole 32, the gap C 1, and the communication notch portion 33, thereby driving the touch panel disposed on the back side of the chassis 22. It is possible to easily connect to the circuit board 26. Further, the insertion hole 32 is arranged at a position offset toward one end (the right side shown in FIG. 10 and the left side shown in FIG. 11) in the X-axis direction of the long side part of the frame-like part 13 a. The opening width is made slightly larger than the width dimension of the flexible substrate 27.
 環状部13bは、図5から図9に示すように、全体として平面に視て横長の方形の短角筒状をなしており、枠状部13aの外周部分13a2の外周縁から表側に向けて突出する第1環状部34と、枠状部13aの外周部分13a2の外周縁から裏側に向けて突出する第2環状部35とを有してなる。言い換えると、短角筒状をなす環状部13bは、その軸線方向(Z軸方向)についての略中央部における内周面に枠状部13aの外周縁が全周にわたって連ねられている。第1環状部34は、枠状部13aに対して表側に配されるタッチパネル14及びカバーパネル15の各外周端面を全周にわたって取り囲む形で配されている。第1環状部34は、その内周面がタッチパネル14及びカバーパネル15の各外周端面と対向状をなしているのに対し、外周面が当該液晶表示装置10の外部に露出していて液晶表示装置10における側面側の外観を構成している。第1環状部34は、枠状部13aからの突出先端位置が、カバーパネル15における外側(表側)の板面よりも裏側に引っ込んでおり、言い換えるとカバーパネル15における外側の板面よりも相対的に低い低位部40を構成している。このため、カバーパネル15における外側の板面は、第1環状部34の突出先端部よりも表側に突き出していて相対的に高くなっている。第1環状部34は、その突出先端位置が全周にわたってほぼ同じ高さに保たれており、全周にわたって低位部40とされている。これにより、カバーパネル15の板面を水平方向と並行させた姿勢で液晶表示装置10を使用している際に、カバーパネル15の外側の板面上に液体がこぼされた場合でも、こぼされた液体は、低位部40(第1環状部34)から速やかに外部へと排出されるようになっていてカバーパネル15の外側の板面上に滞留することが避けられており、もって液体が液晶表示装置10の内部に浸透する事態が生じ難くなっている。さらには、第1環状部34における突出先端面には、外向きに下り勾配をなすテーパ面34aが形成されており、これにより液体の排出を一層円滑化することができる。 As shown in FIGS. 5 to 9, the annular portion 13 b has a horizontally long rectangular short tube shape as viewed in plan as a whole, from the outer peripheral edge of the outer peripheral portion 13 a 2 of the frame-shaped portion 13 a toward the front side. It has the 1st annular part 34 which protrudes, and the 2nd annular part 35 which protrudes toward the back side from the outer periphery of the outer peripheral part 13a2 of the frame-shaped part 13a. In other words, in the annular portion 13b having a short cylindrical shape, the outer peripheral edge of the frame-shaped portion 13a is connected to the inner peripheral surface at the substantially central portion in the axial direction (Z-axis direction) over the entire periphery. The first annular portion 34 is arranged so as to surround the outer peripheral end surfaces of the touch panel 14 and the cover panel 15 arranged on the front side with respect to the frame-shaped portion 13a over the entire circumference. The first annular portion 34 has an inner peripheral surface facing the outer peripheral end surfaces of the touch panel 14 and the cover panel 15, whereas the outer peripheral surface is exposed to the outside of the liquid crystal display device 10, and the liquid crystal display The external appearance of the side surface side of the device 10 is configured. In the first annular portion 34, the protruding tip position from the frame-like portion 13 a is recessed behind the outer (front side) plate surface of the cover panel 15, in other words, relative to the outer plate surface of the cover panel 15. The low-order part 40 which is especially low is comprised. For this reason, the outer plate surface of the cover panel 15 protrudes to the front side relative to the protruding tip portion of the first annular portion 34 and is relatively high. The projecting tip position of the first annular portion 34 is maintained at substantially the same height over the entire circumference, and the first annular portion 34 is a low-order portion 40 over the entire circumference. Accordingly, even when liquid is spilled on the outer plate surface of the cover panel 15 when the liquid crystal display device 10 is used with the plate surface of the cover panel 15 parallel to the horizontal direction, the liquid is spilled. The liquid is quickly discharged from the lower portion 40 (first annular portion 34) to the outside, and is prevented from staying on the outer plate surface of the cover panel 15. It is difficult for a situation to penetrate into the liquid crystal display device 10. Furthermore, a taper surface 34a that forms a downward gradient outward is formed on the projecting tip surface of the first annular portion 34, whereby the liquid can be discharged more smoothly.
 一方、第2環状部35は、図5から図9に示すように、枠状部13aに対して裏側に配されるケーシング16における表側の端部(取付部16c)を外周側から取り囲んでいる。第2環状部35は、その内周面が後述するケーシング16の取付部16cと対向状をなしているのに対し、外周面が当該液晶表示装置10の外部に露出していて液晶表示装置10における側面側の外観を構成している。第2環状部35における突出先端部には、断面鉤型をなすフレーム側係止爪部35aが形成されており、このフレーム側係止爪部35aに対してケーシング16が係止されることで、ケーシング16を取付状態に保持することが可能とされる。 On the other hand, as shown in FIGS. 5 to 9, the second annular portion 35 surrounds the front end portion (attachment portion 16 c) of the casing 16 disposed on the back side with respect to the frame-shaped portion 13 a from the outer peripheral side. . The second annular portion 35 has an inner peripheral surface facing a mounting portion 16c of the casing 16 described later, whereas an outer peripheral surface is exposed to the outside of the liquid crystal display device 10 and the liquid crystal display device 10. The external appearance of the side surface is configured. A frame-side hooking claw portion 35a having a cross-sectional saddle shape is formed at the projecting tip portion of the second annular portion 35, and the casing 16 is locked to the frame-side locking claw portion 35a. The casing 16 can be held in the attached state.
 取付板部13cは、図5から図9に示すように、枠状部13aのうち外周部分13a2から裏側に向けて突出するとともに、枠状部13aの各辺部に沿って延在する板状をなしており、その板面が枠状部13aの板面とほぼ直交している。取付板部13cは、枠状部13aの各辺部毎に個別に配されている。枠状部13aのうちLED基板18側の長辺部に配された取付板部13cは、図5及び図8に示すように、その内側を向いた板面が放熱部材23の第2放熱部23bにおける外側の板面が接する形で取り付けられている。この取付板部13cは、第2放熱部23bに対してネジ部材SMによってネジ止めされており、ネジ部材SMを挿通するネジ挿通孔13c1を有している。また、第2放熱部23bには、ネジ部材SMが螺合されるネジ孔36が形成されている。これにより、第1放熱部23aから第2放熱部23bへと伝達されたLED17からの熱は、取付板部13cへと伝達されてからフレーム13の全体へと伝達されることで、効率的に放熱されるようになっている。また、この取付板部13cは、放熱部材23を介してシャーシ22に対して間接的に固定されている。一方、枠状部13aのうちLED基板18側とは反対側の長辺部及び一対の短辺部にそれぞれ配された各取付板部13cは、図7に示すように、その内側を向いた板面がシャーシ22の各側板22bにおける外側の板面に接する形でネジ部材SMによってそれぞれネジ止めされている。これらの取付板部13cには、ネジ部材SMを挿通するネジ挿通孔13c1が形成されているのに対し、各側板22bには、ネジ部材SMが螺合されるネジ孔36が形成されている。なお、各ネジ部材SMは、各取付板部13cに対してそれぞれの延在方向に沿って複数ずつが間欠的に並ぶ形で取り付けられている。 As shown in FIGS. 5 to 9, the mounting plate portion 13 c protrudes from the outer peripheral portion 13 a 2 toward the back side of the frame-shaped portion 13 a and extends along each side of the frame-shaped portion 13 a. The plate surface is substantially orthogonal to the plate surface of the frame-like portion 13a. The mounting plate portion 13c is individually arranged for each side portion of the frame-like portion 13a. As shown in FIGS. 5 and 8, the mounting plate portion 13 c disposed on the long side portion on the LED substrate 18 side of the frame-shaped portion 13 a has a plate surface facing the inner side as the second heat radiating portion of the heat radiating member 23. It is attached so that the outer plate surface in 23b is in contact. The mounting plate portion 13c is screwed to the second heat radiating portion 23b by a screw member SM, and has a screw insertion hole 13c1 through which the screw member SM is inserted. Further, a screw hole 36 into which the screw member SM is screwed is formed in the second heat radiating portion 23b. Thereby, the heat from the LED 17 transmitted from the first heat radiating portion 23a to the second heat radiating portion 23b is transmitted to the entire plate 13 after being transmitted to the mounting plate portion 13c. Heat is dissipated. Further, the mounting plate portion 13 c is indirectly fixed to the chassis 22 through the heat radiating member 23. On the other hand, the attachment plate portions 13c arranged on the long side portion and the pair of short side portions on the opposite side to the LED substrate 18 side in the frame-like portion 13a face the inside as shown in FIG. The plate surfaces are respectively screwed by the screw members SM so as to be in contact with the outer plate surfaces of the side plates 22b of the chassis 22. The mounting plate portions 13c are formed with screw insertion holes 13c1 through which the screw members SM are inserted, whereas the side plates 22b are formed with screw holes 36 into which the screw members SM are screwed. . In addition, each screw member SM is attached to each attachment plate portion 13c in a form in which a plurality of screw members SM are intermittently arranged along the respective extending directions.
 次に、上記したフレーム13に組み付けられるタッチパネル14について詳しく説明する。タッチパネル14は、図1,図3及び図4に示すように、使用者が液晶パネル11の表示面DSの面内における位置情報を入力するための位置入力装置であり、横長な方形状をなすとともにほぼ透明で優れた透光性を有するガラス製の基板上に所定のタッチパネルパターン(図示せず)が形成されてなる。詳しくは、タッチパネル14は、液晶パネル11と同様に平面に視て横長の方形状をなすガラス製の基板を有しており、その表側を向いた板面にいわゆる投影型静電容量方式のタッチパネルパターンを構成するタッチパネル用透明電極部(図示せず)が形成されており、基板の面内においてタッチパネル用透明電極部が多数個行列状に並列配置されている。タッチパネル14における長辺側の一端部には、フレキシブル基板27の一端側が圧着接続される端子部(図示せず)が形成されており、この端子部がタッチパネルパターンを構成するタッチパネル用透明電極部から引き出された配線の端部に接続されている。この端子部により、フレキシブル基板27を介してタッチパネル駆動回路基板26からの供給される電位を、タッチパネルパターンを構成するタッチパネル用透明電極部へと供給することが可能とされる。タッチパネル14は、その外周部分における内側の板面が、既述した第1固着部材30によってフレーム13の枠状部13aにおける内周部分13a1に対して対向した状態で固着されている。 Next, the touch panel 14 assembled to the frame 13 will be described in detail. As shown in FIGS. 1, 3 and 4, the touch panel 14 is a position input device for a user to input position information in the plane of the display surface DS of the liquid crystal panel 11, and has a horizontally long rectangular shape. At the same time, a predetermined touch panel pattern (not shown) is formed on a glass substrate that is substantially transparent and has excellent translucency. Specifically, the touch panel 14 has a glass substrate that has a horizontally long rectangular shape when seen in a plan view like the liquid crystal panel 11, and a so-called projected capacitive touch panel on the surface facing the front side. A touch panel transparent electrode portion (not shown) constituting the pattern is formed, and a large number of touch panel transparent electrode portions are arranged in parallel in a matrix in the plane of the substrate. A terminal portion (not shown) to which one end side of the flexible substrate 27 is crimped and connected is formed at one end portion on the long side of the touch panel 14, and this terminal portion is formed from the touch panel transparent electrode portion that constitutes the touch panel pattern. It is connected to the end of the drawn wiring. With this terminal portion, it is possible to supply the potential supplied from the touch panel drive circuit substrate 26 via the flexible substrate 27 to the transparent electrode portion for the touch panel constituting the touch panel pattern. The touch panel 14 is fixed in a state where the inner plate surface in the outer peripheral portion thereof is opposed to the inner peripheral portion 13a1 in the frame-like portion 13a of the frame 13 by the first fixing member 30 described above.
 続いて、上記したフレーム13に組み付けられるカバーパネル15について詳しく説明する。カバーパネル15は、図1から図4に示すように、タッチパネル14を表側からその全域にわたって覆う形で配されており、それによりタッチパネル14及び液晶パネル11の保護が図られている。カバーパネル15は、フレーム13における枠状部13aを表側から全域にわたって覆うとともに、液晶表示装置10における正面側の外観を構成している。カバーパネル15は、横長な方形状をなすとともにほぼ透明で優れた透光性を有するガラス製で板状の基材からなり、好ましくは強化ガラスからなる。カバーパネル15に用いられる強化ガラスとしては、例えば板状のガラス基材の表面に化学強化処理が施されることで、表面に化学強化層を備えた化学強化ガラスを用いることが好ましい。この化学強化処理は、例えばガラス材料に含まれるアルカリ金属イオンを、それよりもイオン半径が大きいアルカリ金属イオンとイオン交換により置換することで、板状のガラス基材の強化を図る処理をいい、その結果形成される化学強化層は圧縮応力が残留した圧縮応力層(イオン交換層)とされる。これにより、カバーパネル15は、機械的強度及び耐衝撃性能が高いものとされているから、その裏側に配されるタッチパネル14及び液晶パネル11が破損したり、傷付くのをより確実に防止することができる。 Subsequently, the cover panel 15 assembled to the frame 13 will be described in detail. As shown in FIGS. 1 to 4, the cover panel 15 is disposed so as to cover the touch panel 14 from the front side over the entire region thereof, thereby protecting the touch panel 14 and the liquid crystal panel 11. The cover panel 15 covers the entire frame-like portion 13a of the frame 13 from the front side to the entire area, and configures the front side appearance of the liquid crystal display device 10. The cover panel 15 is made of a plate-like base material made of glass having a horizontally long rectangular shape and substantially transparent and having excellent translucency, and preferably made of tempered glass. As the tempered glass used for the cover panel 15, it is preferable to use chemically tempered glass having a chemically strengthened layer on the surface, for example, by subjecting the surface of a plate-like glass substrate to chemical tempering treatment. This chemical strengthening treatment refers to, for example, a treatment for strengthening the plate-shaped glass substrate by replacing alkali metal ions contained in the glass material by ion exchange with alkali metal ions having a larger ion radius than that, The resulting chemically strengthened layer is a compressive stress layer (ion exchange layer) in which compressive stress remains. Thereby, since the cover panel 15 has high mechanical strength and impact resistance, the touch panel 14 and the liquid crystal panel 11 disposed on the back side of the cover panel 15 are more reliably prevented from being damaged or damaged. be able to.
 カバーパネル15は、図3及び図4に示すように、液晶パネル11及びタッチパネル14と同様に平面に視て横長の方形状をなしており、その平面に視た大きさは液晶パネル11及びタッチパネル14よりも一回り大きなものとされる。従って、カバーパネル15は、図5及び図7に示すように、液晶パネル11及びタッチパネル14における各外周縁から全周にわたって庇状に外側に張り出す張出部分15EPを有している。この張出部分15EPは、液晶パネル11及びタッチパネル14を取り囲む横長で方形の略枠状(略額縁状)をなしており、その内側の板面が、既述した第2固着部材31によってフレーム13の枠状部13aにおける外周部分13a2に対して対向した状態で固着されている。一方、カバーパネル15のうちタッチパネル14と対向状をなす中央部分は、反射防止フィルムARを介してタッチパネル14に対して表側に積層されている。また、既述した通り、カバーパネル15における外側(表側)の板面は、フレーム13の第1環状部34の突出先端部よりも表側に突き出していて相対的に高くなっている。 As shown in FIGS. 3 and 4, the cover panel 15 has a horizontally long rectangular shape when viewed in a plane, like the liquid crystal panel 11 and the touch panel 14, and the size of the cover panel 15 viewed in the plane is the liquid crystal panel 11 and the touch panel. It is supposed to be one size larger than 14. Therefore, as shown in FIGS. 5 and 7, the cover panel 15 has an overhanging portion 15EP that projects outwardly in a bowl shape from the outer peripheral edges of the liquid crystal panel 11 and the touch panel 14 over the entire periphery. This overhanging portion 15EP has a horizontally long and substantially rectangular frame shape (substantially frame shape) that surrounds the liquid crystal panel 11 and the touch panel 14, and the inner plate surface thereof is framed by the second fixing member 31 described above. The frame-shaped portion 13a is fixed to the outer peripheral portion 13a2 so as to face the outer peripheral portion 13a2. On the other hand, a central portion of the cover panel 15 that faces the touch panel 14 is laminated on the front side with respect to the touch panel 14 via an antireflection film AR. In addition, as described above, the outer (front side) plate surface of the cover panel 15 protrudes to the front side relative to the protruding tip of the first annular portion 34 of the frame 13 and is relatively high.
 カバーパネル15のうち上記した張出部分15EPを含む外周部分における内側(裏側)の板面(タッチパネル14側を向いた板面)には、図2,図5及び図7に示すように、光を遮る板面遮光層(遮光層、板面遮光部)41が形成されている。板面遮光層41は、例えば黒色を呈する塗料などの遮光性材料からなるものとされ、その遮光性材料を、カバーパネル15における内側の板面に印刷することで同板面に一体的に設けられている。なお、板面遮光層41を設けるに際しては、例えばスクリーン印刷、インクジェット印刷などの印刷手段を採用することができる。板面遮光層41は、カバーパネル15のうち張出部分15EPの全域に加えて、張出部分15EPよりも内側にあって、タッチパネル14及び液晶パネル11の各外周部分と平面に視てそれぞれ重畳する部分にわたる範囲に形成されている。従って、板面遮光層41は、液晶パネル11の表示領域を取り囲む形で配されることになるので、表示領域外の光を遮ることができ、もって表示領域に表示される画像に係る表示品位を高いものとすることができる。なお、図2では、板面遮光層41の形成範囲を網掛け状にして示している。 As shown in FIGS. 2, 5, and 7, on the inner (back side) plate surface (the plate surface facing the touch panel 14 side) of the outer peripheral portion including the above-described overhang portion 15 EP of the cover panel 15, A plate surface light shielding layer (light shielding layer, plate surface light shielding portion) 41 is formed. The plate surface light shielding layer 41 is made of, for example, a light shielding material such as a black paint, and the light shielding material is integrally provided on the plate surface by printing on the inner plate surface of the cover panel 15. It has been. In providing the plate surface light shielding layer 41, for example, printing means such as screen printing and ink jet printing can be employed. The plate surface light-shielding layer 41 is inside the overhanging portion 15EP in addition to the entire area of the overhanging portion 15EP of the cover panel 15, and overlaps each of the outer peripheral portions of the touch panel 14 and the liquid crystal panel 11 in a plan view. It is formed in a range over the part to be. Therefore, since the plate surface light shielding layer 41 is disposed so as to surround the display area of the liquid crystal panel 11, it is possible to block light outside the display area, and thus display quality related to an image displayed in the display area. Can be high. In FIG. 2, the formation range of the plate surface light-shielding layer 41 is shown in a shaded shape.
 続いて、上記したフレーム13に組み付けられるケーシング16について詳しく説明する。ケーシング16は、合成樹脂材料または金属材料からなるものであって、図1,図3及び図4に示すように、表側に向けて開口した略椀型(略ボウル型)をなしており、フレーム13の枠状部13a、取付板部13c、シャーシ22、放熱部材23、及びタッチパネル駆動回路基板26などの部材を裏側から覆うとともに、液晶表示装置10における背面側の外観を構成している。ケーシング16は、概ね平坦な底部16aと、底部16aの外周縁から表側へ向けて立ち上がるとともに断面湾曲形状をなす曲部16bと、曲部16bの外周縁から表側へ向けてほぼ真っ直ぐに立ち上がる取付部16cとからなる。取付部16cには、図5及び図7に示すように、断面鉤型をなすケーシング側係止爪部16dが形成されており、このケーシング側係止爪部16dがフレーム13のフレーム側係止爪部35aに対して係止されることで、ケーシング16をフレーム13に対して取付状態に保持することが可能とされる。 Subsequently, the casing 16 assembled to the frame 13 will be described in detail. The casing 16 is made of a synthetic resin material or a metal material, and as shown in FIGS. 1, 3, and 4, has a substantially bowl shape that is open toward the front side. 13 covers the members such as the frame portion 13a, the mounting plate portion 13c, the chassis 22, the heat radiating member 23, and the touch panel drive circuit board 26 from the back side, and configures the appearance of the back side of the liquid crystal display device 10. The casing 16 has a generally flat bottom portion 16a, a curved portion 16b that rises from the outer peripheral edge of the bottom portion 16a toward the front side and has a curved cross section, and an attachment portion that rises substantially straight from the outer peripheral edge of the curved portion 16b toward the front side. 16c. As shown in FIGS. 5 and 7, a casing-side locking claw portion 16 d having a saddle-shaped cross section is formed on the mounting portion 16 c, and the casing-side locking claw portion 16 d is locked to the frame 13 on the frame side. The casing 16 can be held in an attached state with respect to the frame 13 by being locked to the claw portion 35a.
 ところで、本実施形態に係る液晶表示装置10では、図5に示すように、タッチパネル14の外周部分と液晶パネル11の外周部分との間には、枠状をなすフレーム13が介在する形で配されることで、タッチパネル14と液晶パネル11との間に隙間C2が確保されているので、例えばカバーパネル15に外力が作用してカバーパネル15と共にタッチパネル14が液晶パネル11側に撓むよう変形した場合でも、撓んだタッチパネル14が液晶パネル11に干渉し難くなる。これにより、液晶パネル11に表示される画像に表示不良が発生する事態が生じ難くなり、表示品位に優れる。また、仮にフレーム13を用いず、タッチパネル14を液晶パネル11に対して直接貼り付けるようにした場合に比べると、タッチパネル14と液晶パネル11との対向面間の間隔をその面内において容易に均一化することができるとともにコスト面でも優れる。その上で、フレーム13には、タッチパネル14の端部と、液晶パネル11に対してタッチパネル14側とは反対側に配されたタッチパネル駆動回路基板26とを電気的に接続するフレキシブル基板27を挿通する挿通孔32が形成されているので、タッチパネル14の外周部分及びカバーパネル15の張出部分15EPがフレーム13により液晶パネル11側から受けられているにも拘わらず、フレキシブル基板27を容易に引き回すことができるのに加えて、仮にフレキシブル基板をフレーム13の外側に回り込ませた場合に比べると、フレキシブル基板27を短くすることができるとともに当該液晶表示装置10の額縁部分を狭くすることができる。 By the way, in the liquid crystal display device 10 according to the present embodiment, as shown in FIG. 5, a frame-like frame 13 is interposed between the outer peripheral portion of the touch panel 14 and the outer peripheral portion of the liquid crystal panel 11. As a result, a gap C2 is secured between the touch panel 14 and the liquid crystal panel 11, so that, for example, an external force acts on the cover panel 15 and the touch panel 14 is deformed so as to bend toward the liquid crystal panel 11 together with the cover panel 15. Even in this case, the bent touch panel 14 is less likely to interfere with the liquid crystal panel 11. This makes it difficult for a display defect to occur in the image displayed on the liquid crystal panel 11, and the display quality is excellent. Further, compared to the case where the touch panel 14 is directly attached to the liquid crystal panel 11 without using the frame 13, the distance between the facing surfaces of the touch panel 14 and the liquid crystal panel 11 is easily uniform in the plane. And cost is excellent. In addition, a flexible substrate 27 that electrically connects the end of the touch panel 14 and the touch panel drive circuit substrate 26 disposed on the opposite side of the touch panel 14 to the liquid crystal panel 11 is inserted into the frame 13. Since the insertion hole 32 is formed, the flexible substrate 27 is easily routed even though the outer peripheral portion of the touch panel 14 and the overhanging portion 15EP of the cover panel 15 are received from the liquid crystal panel 11 side by the frame 13. In addition, the flexible substrate 27 can be shortened and the frame portion of the liquid crystal display device 10 can be narrowed as compared with the case where the flexible substrate is wound around the outside of the frame 13.
 上記したタッチパネル14の外周部分及びカバーパネル15の張出部分15EPは、図5に示すように、フレーム13の枠状部13aに対してそれぞれ第1固着部材30及び第2固着部材31によって固着されることで取付状態に保持されているのに対し、挿通孔32は、フレーム13の枠状部13aにおいて第1固着部材30と第2固着部材31との間に位置して配されているから、タッチパネル14及びカバーパネル15の安定的な保持を図ることができるのに加えて、タッチパネル14の端部に接続されるとともに両固着部材30,31の間に挟まれた空間に配されたフレキシブル基板27を挿通孔32に挿通することで、タッチパネル14及びカバーパネル15の固着を妨げることなく、フレキシブル基板27をタッチパネル駆動回路基板26へと接続することができる。しかも、カバーパネル15の外周部分の板面には、タッチパネル14及び液晶パネル11の各外周部分に加えて挿通孔32とも平面視重畳する形で板面遮光層41が形成されているから、タッチパネル14及び液晶パネル11の各外周部分に加えて挿通孔32が液晶表示装置10の使用者に見え難くすることができ、もって外観を良好なものとすることができるとともに、表示画像に係る表示品位を高いものとすることができる。さらには、フレーム13のうち環状部13bが液晶表示装置10の側面側の外観を構成しているので、仮にフレキシブル基板をフレーム13の外側に回り込ませると、フレキシブル基板が外部に露出することになるものの、本実施形態では挿通孔32に通すことでフレキシブル基板27を液晶表示装置10の内部空間にて引き回すことができるから、外観に優れる。 The outer peripheral portion of the touch panel 14 and the overhang portion 15EP of the cover panel 15 are fixed to the frame-like portion 13a of the frame 13 by the first fixing member 30 and the second fixing member 31, respectively, as shown in FIG. The insertion hole 32 is disposed between the first fixing member 30 and the second fixing member 31 in the frame-like portion 13a of the frame 13 while being held in the attached state. In addition to being able to stably hold the touch panel 14 and the cover panel 15, the flexible panel is connected to the end of the touch panel 14 and is disposed in a space sandwiched between the fixing members 30 and 31. By inserting the substrate 27 into the insertion hole 32, the flexible substrate 27 is driven by the touch panel without preventing the touch panel 14 and the cover panel 15 from being fixed. It can be connected to the road substrate 26. In addition, since the plate surface light-shielding layer 41 is formed on the plate surface of the outer peripheral portion of the cover panel 15 so as to overlap with the insertion holes 32 in addition to the outer peripheral portions of the touch panel 14 and the liquid crystal panel 11, the touch panel. 14 and the respective outer peripheral portions of the liquid crystal panel 11, the insertion hole 32 can be made difficult to be seen by the user of the liquid crystal display device 10, so that the appearance can be improved and the display quality of the display image can be improved. Can be high. Furthermore, since the annular portion 13b of the frame 13 forms the appearance of the side surface side of the liquid crystal display device 10, if the flexible substrate is turned around to the outside of the frame 13, the flexible substrate is exposed to the outside. However, in this embodiment, since the flexible substrate 27 can be routed in the internal space of the liquid crystal display device 10 by passing through the insertion hole 32, the appearance is excellent.
 ここで、本実施形態に係る液晶表示装置10では、図5に示すように、液晶パネル11及び導光板19が互いに重なる形で配された状態でシャーシ22とフレーム13との間に挟み込まれる形で保持されており、従来のように導光板19と液晶パネル11との間にパネル受け部材が介在する構成となっていないから、シャーシ22及びフレーム13の保持力によっては導光板19が板厚方向について位置ずれするおそれがある。それに加えて、従来のパネル受け部材が廃止されると、全体の薄型化が図られるとともに導光板19自体がより薄型化される傾向にあるため、LED17に対して導光板19をより高い精度でもって位置合わせすることが求められる傾向にある。その点、本実施形態に係るシャーシ22の一部がLED基板18が取り付けられる基板取付部37とされているから、仮にLED基板18をシャーシ22とは別の放熱部材に取り付け、その放熱部材を基板取付部37の内側の板面に接する形で取り付けるようにした場合に比べると、LED基板18と基板取付部37との間に生じ得る組み付け誤差を小さくすることができる。それに加えて、LED基板18を基板取付部37における光入射面19bとの対向面に直接取り付けることで、LED17を光入射面19bに対して対向状に配置しつつ光入射面19bに沿う方向について容易に位置合わせすることができる。これにより、導光板19の光入射面19bに沿う方向について光入射面19bとLED17との間に生じ得る位置ずれを低減させることができ、特にLED17からの発光光のうち発光強度が最も高い光の進行方向である光軸を導光板19に対してその板厚方向についての中央位置と一致させる上で好適となる。従って、LED17から導光板19の光入射面19bに入射される光の入射効率を向上させることができるとともに、導光板19の光出射面19aからの出射光に輝度ムラが生じ難くなる。 Here, in the liquid crystal display device 10 according to the present embodiment, as shown in FIG. 5, the liquid crystal panel 11 and the light guide plate 19 are sandwiched between the chassis 22 and the frame 13 in a state where they overlap each other. Since the panel receiving member is not interposed between the light guide plate 19 and the liquid crystal panel 11 as in the prior art, the thickness of the light guide plate 19 depends on the holding force of the chassis 22 and the frame 13. There is a risk of displacement in the direction. In addition, when the conventional panel receiving member is abolished, the overall thickness can be reduced and the light guide plate 19 itself tends to be made thinner. Therefore, there is a tendency to require alignment. In that respect, since a part of the chassis 22 according to the present embodiment is a board attaching portion 37 to which the LED board 18 is attached, the LED board 18 is temporarily attached to a heat radiating member different from the chassis 22 and the heat radiating member is attached. Compared with the case where the board is attached so as to be in contact with the inner plate surface of the board attachment portion 37, the assembly error that can occur between the LED board 18 and the board attachment portion 37 can be reduced. In addition, by directly attaching the LED substrate 18 to the surface of the substrate mounting portion 37 that faces the light incident surface 19b, the LED 17 is disposed facing the light incident surface 19b, and the direction along the light incident surface 19b. Can be easily aligned. Thereby, it is possible to reduce a positional shift that may occur between the light incident surface 19b and the LED 17 in the direction along the light incident surface 19b of the light guide plate 19, and in particular, light having the highest emission intensity among the emitted light from the LED 17. This is suitable for aligning the optical axis, which is the traveling direction, with the light guide plate 19 at the center position in the thickness direction. Accordingly, it is possible to improve the incident efficiency of light incident on the light incident surface 19b of the light guide plate 19 from the LED 17, and it is difficult for luminance unevenness to occur in the emitted light from the light output surface 19a of the light guide plate 19.
 しかも、シャーシ22には、導光板支持部22a1よりも裏側に膨出することで、基板取付部37に取り付けられたLED基板18を収容する基板収容部22a2が設けられているから、LED基板18の収容スペースを十分に確保することができる。これにより、LED17のZ軸方向についての寸法を自由に設定することができ、例えば導光板19の板厚寸法に近い寸法とすることができるので、LED17から導光板19の光入射面19bに入射する光の入射光量を極めて高いものとすることができ、もって入射効率の最適化を図る上で好適となっている。 In addition, since the chassis 22 is provided with a board accommodating portion 22a2 that accommodates the LED board 18 attached to the board attaching portion 37 by bulging out from the light guide plate support portion 22a1, the LED substrate 18 is provided. It is possible to secure a sufficient storage space. Thereby, the dimension about the Z-axis direction of LED17 can be set freely, for example, since it can be set as the dimension close | similar to the board thickness dimension of the light-guide plate 19, it injects into the light-incidence surface 19b of the light-guide plate 19 from LED17. The amount of incident light can be made extremely high, which is suitable for optimizing the incident efficiency.
 上記したようにLED基板18がシャーシ22の一部である基板取付部37に対して直接取り付けられる構成では、仮にLED基板18が放熱部材を介して基板取付部37に取り付けられる構成に比べると、放熱性能の観点では劣ることとなる。その点、本実施形態では、基板収容部37の外面に接する形で放熱部材23を取り付けるようにしているから、LED17からの熱を、LED基板18、基板取付部37、及び基板収容部22a2を介して導光板支持部22a1及び放熱部材23へと伝達させることで、効率的な放熱を図ることができる。しかも、放熱部材23を構成する第2放熱部23bがフレーム13に設けられた取付板部13cに接する形で取り付けられることで、シャーシ22及び放熱部材23に加えてフレーム13を利用してLED17の放熱を図ることができ、放熱性能を一層向上させることができる。その上で、フレーム13の枠状部13aには、挿通孔32が基板取付部37と取付板部13cとの間に位置して配されているのに対し、放熱部材23には、挿通孔32に連通することでフレキシブル基板27を通す連通切欠部33が形成されているから、フレキシブル基板27を挿通孔32及び連通切欠部33に通すことでタッチパネル駆動回路基板26へと容易に接続することができる。さらには、放熱部材23の第2放熱部23bと基板取付部37との間に有される隙間C1に対して挿通孔32が臨む位置に配されているから、フレキシブル基板27を挿通孔32、隙間C1、及び連通切欠部33に通すことで、タッチパネル駆動回路基板26へと一層容易に接続することができる。 As described above, in the configuration in which the LED substrate 18 is directly attached to the substrate attachment portion 37 that is a part of the chassis 22, the LED substrate 18 is temporarily attached to the substrate attachment portion 37 via the heat dissipation member. This is inferior in terms of heat dissipation performance. In that respect, in this embodiment, since the heat radiating member 23 is attached so as to be in contact with the outer surface of the substrate housing portion 37, the heat from the LED 17 is applied to the LED substrate 18, the substrate mounting portion 37, and the substrate housing portion 22a2. By transmitting the light to the light guide plate support 22a1 and the heat radiating member 23, efficient heat dissipation can be achieved. In addition, since the second heat radiating portion 23b constituting the heat radiating member 23 is attached in contact with the mounting plate portion 13c provided on the frame 13, the frame 17 is used in addition to the chassis 22 and the heat radiating member 23. Heat dissipation can be achieved, and the heat dissipation performance can be further improved. In addition, the insertion hole 32 is disposed in the frame-like portion 13a of the frame 13 between the board attachment portion 37 and the attachment plate portion 13c, whereas the insertion hole 32 is provided in the heat dissipation member 23. Since the communication cutout portion 33 through which the flexible substrate 27 is passed is formed by communicating with 32, the flexible substrate 27 can be easily connected to the touch panel drive circuit substrate 26 by passing through the insertion hole 32 and the communication cutout portion 33. Can do. Further, since the insertion hole 32 faces the gap C1 between the second heat radiation part 23b of the heat radiation member 23 and the board mounting part 37, the flexible board 27 is inserted into the insertion hole 32, By passing through the gap C <b> 1 and the communication notch 33, the touch panel drive circuit board 26 can be more easily connected.
 以上説明したように本実施形態の液晶表示装置(表示装置)10は、画像を表示する表示面DSを有する液晶パネル(表示パネル)11と、透光性を有するものであって、液晶パネル11の表示面DSに対して対向状をなす対向面を有するタッチパネル(機能性板状部材)14と、タッチパネル14を保護するとともに透光性を有するものであって、タッチパネル14に対して液晶パネル11側とは反対側に配されて対向状をなす対向面を有するとともに、タッチパネル14の外縁よりも外側に張り出す張出部分15EPを有するカバーパネル(保護板材)15と、液晶パネル11に対してタッチパネル14側とは反対側に配されるとともに、タッチパネル14の機能を実現するための駆動を制御するタッチパネル駆動回路基板(制御部材)26と、一端側がタッチパネル14の端部に電気的に接続されるのに対し、他端側がタッチパネル駆動回路基板26に電気的に接続されるフレキシブル基板(接続部材)27と、カバーパネル15の張出部分15EP及びタッチパネル14の外周部分に倣う枠状をなすとともに、カバーパネル15の張出部分15EP及びタッチパネル14の外周部分を液晶パネル11側で受け、且つタッチパネル14の外周部分と液晶パネル11の外周部分との間に介在する形で配されるものであって、フレキシブル基板27を挿通する挿通孔32が形成されてなるフレーム13と、を備える。 As described above, the liquid crystal display device (display device) 10 of the present embodiment has a liquid crystal panel (display panel) 11 having a display surface DS for displaying an image and a light-transmitting property. The touch panel (functional plate member) 14 having a facing surface that is opposed to the display surface DS, and the touch panel 14 is protected and translucent. The liquid crystal panel 11 has a cover panel (protective plate material) 15 having an opposing surface disposed opposite to the side and having an opposing surface and an overhanging portion 15EP projecting outward from the outer edge of the touch panel 14. A touch panel drive circuit board (control member) that is disposed on the side opposite to the touch panel 14 side and controls driving for realizing the function of the touch panel 14 26, one end side of which is electrically connected to the end portion of the touch panel 14, while the other end side is electrically connected to the touch panel drive circuit board 26, and the cover panel 15 is stretched. It forms a frame shape that follows the protruding portion 15EP and the outer peripheral portion of the touch panel 14, receives the protruding portion 15EP of the cover panel 15 and the outer peripheral portion of the touch panel 14 on the liquid crystal panel 11 side, and the outer peripheral portion of the touch panel 14 and the liquid crystal panel 11 And a frame 13 formed with an insertion hole 32 through which the flexible substrate 27 is inserted.
 このようにすれば、液晶パネル11の表示面DSに表示された画像は、共に透光性を有するタッチパネル14及びカバーパネル15を介して当該液晶表示装置10の使用者に観察される。タッチパネル14は、その外側に張り出す張出部分15EPを有するカバーパネル15によって保護が図られており、フレキシブル基板27を介して電気的に接続されたタッチパネル駆動回路基板26によってその駆動が制御される。タッチパネル14の外周部分と液晶パネル11の外周部分との間には、枠状をなすフレーム13が介在する形で配されることで、タッチパネル14と液晶パネル11との間に隙間C2を確保することが可能となるので、例えばカバーパネル15を介してタッチパネル14に外力が作用してタッチパネル14が液晶パネル11側に撓むよう変形した場合でも、撓んだタッチパネル14が液晶パネル11に干渉し難くなる。これにより、液晶パネル11に表示される画像に表示不良が発生する事態が生じ難くなり、表示品位に優れる。また、仮にフレームを用いず、タッチパネル14を液晶パネル11に対して直接貼り付けるようにした場合に比べると、タッチパネル14と液晶パネル11との対向面間の間隔をその面内において容易に均一化することができるとともにコスト面でも優れる。 In this manner, the image displayed on the display surface DS of the liquid crystal panel 11 is observed by the user of the liquid crystal display device 10 through the translucent touch panel 14 and the cover panel 15. The touch panel 14 is protected by a cover panel 15 having an overhanging portion 15EP projecting to the outside, and the driving of the touch panel 14 is controlled by a touch panel drive circuit board 26 electrically connected through a flexible board 27. . Between the outer peripheral part of the touch panel 14 and the outer peripheral part of the liquid crystal panel 11, a gap C <b> 2 is ensured between the touch panel 14 and the liquid crystal panel 11 by arranging the frame 13 having a frame shape. Therefore, for example, even when an external force acts on the touch panel 14 through the cover panel 15 and the touch panel 14 is deformed to bend toward the liquid crystal panel 11, the bent touch panel 14 is unlikely to interfere with the liquid crystal panel 11. Become. This makes it difficult for a display defect to occur in the image displayed on the liquid crystal panel 11, and the display quality is excellent. Further, compared to the case where the touch panel 14 is directly attached to the liquid crystal panel 11 without using a frame, the distance between the facing surfaces of the touch panel 14 and the liquid crystal panel 11 is easily uniformized within the surface. It can be done and is excellent in terms of cost.
 そして、フレーム13には、タッチパネル14の端部と、液晶パネル11に対してタッチパネル14側とは反対側に配されたタッチパネル駆動回路基板26とを電気的に接続するフレキシブル基板27を挿通する挿通孔32が形成されているので、タッチパネル14の外周部分及びカバーパネル15の張出部分15EPがフレーム13により液晶パネル11側から受けられているにも拘わらず、フレキシブル基板27を容易に引き回すことができるのに加えて、仮にフレキシブル基板をフレーム13の外側に回り込ませた場合に比べると、フレキシブル基板27を短くすることができるとともに当該液晶表示装置10の額縁部分を狭くすることができる。このように本実施形態によれば、フレキシブル基板27の引き回しを容易に図ることができる。 The frame 13 is inserted through a flexible substrate 27 that electrically connects the end of the touch panel 14 and the touch panel drive circuit substrate 26 disposed on the opposite side of the liquid crystal panel 11 from the touch panel 14 side. Since the hole 32 is formed, the flexible substrate 27 can be easily routed even though the outer peripheral portion of the touch panel 14 and the protruding portion 15EP of the cover panel 15 are received from the liquid crystal panel 11 side by the frame 13. In addition, the flexible substrate 27 can be shortened and the frame portion of the liquid crystal display device 10 can be narrowed as compared with the case where the flexible substrate is wound around the outside of the frame 13. As described above, according to the present embodiment, the flexible substrate 27 can be easily routed.
 また、カバーパネル15の外周部分の板面には、タッチパネル14及び液晶パネル11の各外周部分とそれぞれ重畳するとともに挿通孔32と重畳する形で光を遮る板面遮光層(遮光層)41が形成されている。このようにすれば、板面遮光層41によってタッチパネル14及び液晶パネル11の各外周部分が当該液晶表示装置10の使用者に視認されるのを防ぐことができるのに加えて、フレーム13に形成された挿通孔32が使用者に視認されるのを防ぐことができる。これにより、外観に優れるとともに液晶パネル11の表示面DSに表示される画像に係る表示品位を高めることができる。 Further, on the plate surface of the outer peripheral portion of the cover panel 15, there is a plate surface light-shielding layer (light-shielding layer) 41 that shields light in a form that overlaps with the outer peripheral portions of the touch panel 14 and the liquid crystal panel 11 and overlaps with the insertion hole 32. Is formed. In this manner, the outer peripheral portions of the touch panel 14 and the liquid crystal panel 11 can be prevented from being visually recognized by the user of the liquid crystal display device 10 by the plate surface light shielding layer 41, and also formed on the frame 13. It is possible to prevent the inserted insertion hole 32 from being visually recognized by the user. Thereby, it is possible to improve the display quality related to the image displayed on the display surface DS of the liquid crystal panel 11 while being excellent in appearance.
 また、フレーム13には、タッチパネル14の外周部分及びカバーパネル15の張出部分15EPが取り付けられている。このようにすれば、フレーム13には、タッチパネル14の外周部分及びカバーパネル15の張出部分15EPが取り付けられることでそれぞれの保持が図られているので、仮にカバーパネル15をフレーム13側とは反対側から押さえる部材を用いて保持を図るようにした場合に比べると、部品点数を削減することができるとともに、外観上も優れる。 Further, the outer peripheral portion of the touch panel 14 and the overhang portion 15EP of the cover panel 15 are attached to the frame 13. In this manner, the outer peripheral portion of the touch panel 14 and the overhanging portion 15EP of the cover panel 15 are attached to the frame 13, so that the respective holding is achieved. Compared with the case where holding is performed using a member pressed from the opposite side, the number of parts can be reduced and the appearance is also excellent.
 また、タッチパネル14の外周部分とフレーム13とを固着する第1固着部材30と、カバーパネル15の張出部分15EPとフレーム13とを固着する第2固着部材31とが備えられており、挿通孔32は、フレーム13において第1固着部材30と第2固着部材31との間に位置して配されている。このようにすれば、第1固着部材30及び第2固着部材31によってタッチパネル14及びカバーパネル15がフレーム13に対して固着されて安定的な保持が図られる。挿通孔32は、フレーム13において第1固着部材30と第2固着部材31との間に位置して配されることで、タッチパネル14及びカバーパネル15の固着を妨げることなく、フレキシブル基板27の挿通を図ることができる。 Further, a first fixing member 30 for fixing the outer peripheral portion of the touch panel 14 and the frame 13 and a second fixing member 31 for fixing the protruding portion 15EP of the cover panel 15 and the frame 13 are provided, and the insertion hole 32 is arranged between the first fixing member 30 and the second fixing member 31 in the frame 13. In this way, the touch panel 14 and the cover panel 15 are fixed to the frame 13 by the first fixing member 30 and the second fixing member 31, and stable holding is achieved. The insertion hole 32 is disposed between the first fixing member 30 and the second fixing member 31 in the frame 13 so that the flexible substrate 27 can be inserted without preventing the touch panel 14 and the cover panel 15 from being fixed. Can be achieved.
 また、フレーム13は、少なくとも一部が外部に露出することで当該液晶表示装置10の外観を構成している。このようにすれば、フレーム13が当該液晶表示装置10の外観を構成しているので、仮にフレキシブル基板をフレーム13の外側に回り込ませた場合には、フレキシブル基板が外部に露出することになるものの、挿通孔32によってフレキシブル基板27を当該液晶表示装置10の内部に配置することができ、外観に優れる。また、仮にフレキシブル基板をフレーム13の外側に回り込ませたとき、フレキシブル基板を覆う部材を追加することが考えられるが、それに比べると、部品点数が少なく済むとともに全体を小型に保つことができる。 Further, at least a part of the frame 13 is exposed to the outside, so that the appearance of the liquid crystal display device 10 is configured. In this case, since the frame 13 constitutes the appearance of the liquid crystal display device 10, if the flexible substrate is wrapped around the outside of the frame 13, the flexible substrate is exposed to the outside. The flexible substrate 27 can be disposed inside the liquid crystal display device 10 by the insertion hole 32, and the appearance is excellent. In addition, when the flexible board is wound around the outside of the frame 13, it may be possible to add a member that covers the flexible board.
 また、液晶パネル11に対して表示面DS側とは反対側に配されるとともに、液晶パネル11に光を供給するバックライト装置(照明装置)12が備えられており、バックライト装置12は、LED(光源)17と、液晶パネル11に対して表示面DS側とは反対側に重なる形で配されるとともに、端面である光入射面19bがLED17と対向状をなし、板面である光出射面19aから液晶パネル11へ向けて光を出射させる導光板19と、フレーム13との間で液晶パネル11及び導光板19を挟み込む形で保持し且つLED17を収容するシャーシ22とを有している。このようにすれば、LED17からの光が導光板19の端面である光入射面19bに入射されると、導光板19内を伝播されてから液晶パネル11へ向けて出射される。液晶パネル11では、バックライト装置12から供給された光を利用して表示面DSに画像が表示される。タッチパネル14と液晶パネル11との間に介在するフレーム13によって、液晶パネル11及び導光板19をシャーシ22との間で挟み込む形で保持することができる。これにより、仮に導光板19と液晶パネル11との間に枠状の部材を介在させた場合に比べると、当該液晶表示装置10の薄型化を図ることができるとともに、部品点数の削減を図ることができる。 In addition, a backlight device (illumination device) 12 that supplies light to the liquid crystal panel 11 is provided on the side opposite to the display surface DS side with respect to the liquid crystal panel 11. The LED (light source) 17 and the liquid crystal panel 11 are arranged so as to overlap with the side opposite to the display surface DS side, and the light incident surface 19b which is an end surface is opposed to the LED 17 and is a plate surface. A light guide plate 19 that emits light from the emission surface 19 a toward the liquid crystal panel 11, and a chassis 22 that holds the liquid crystal panel 11 and the light guide plate 19 between the frame 13 and accommodates the LEDs 17. Yes. In this way, when the light from the LED 17 is incident on the light incident surface 19 b that is the end surface of the light guide plate 19, it is propagated through the light guide plate 19 and then emitted toward the liquid crystal panel 11. In the liquid crystal panel 11, an image is displayed on the display surface DS using the light supplied from the backlight device 12. The liquid crystal panel 11 and the light guide plate 19 can be held between the chassis 22 and the frame 13 interposed between the touch panel 14 and the liquid crystal panel 11. Thereby, compared with the case where a frame-shaped member is interposed between the light guide plate 19 and the liquid crystal panel 11, the liquid crystal display device 10 can be made thinner and the number of parts can be reduced. Can do.
 また、バックライト装置12には、LED17が設けられるLED基板(光源基板)18が備えられており、シャーシ22の一部は、導光板19の端面である光入射面19bと対向状をなす対向面を有し、その対向面にLED基板18が取り付けられてなる基板取付部37とされている。このようにすれば、液晶パネル11及び導光板19は、互いに重なる形で配された状態でシャーシ22とフレーム13との間に挟み込まれる形で保持されており、導光板19と液晶パネル11との間に枠状の部材が介在する構成となっていないから、シャーシ22及びフレーム13の保持力によっては導光板19が板厚方向について位置ずれするおそれがある。その点、上記したようにシャーシ22の一部は、導光板19の端面である光入射面19bと対向状をなす対向面を有し、その対向面にLED基板18が取り付けられる基板取付部37とされているから、仮にLED基板18をシャーシ22とは別の部材に取り付け、その部材を基板取付部37に取り付けるようにした場合に比べると、LED基板18と基板取付部37との間に生じ得る組み付け誤差を小さくすることができる。それに加えて、LED基板18を基板取付部37における導光板19の端面である光入射面19bとの対向面に直接取り付けることで、LED17を導光板19の端面である光入射面19bに対して対向状に配置しつつ同端面である光入射面19bに沿う方向について容易に位置合わせすることができる。これにより、導光板19の端面である光入射面19bに沿う方向について同端面である光入射面19bとLED17との間に生じ得る位置ずれを低減させることができる。従って、LED17から導光板19の端面である光入射面19bに入射される光の入射効率を向上させることができるとともに、導光板19の板面である光出射面19aからの出射光に輝度ムラが生じ難くなる。 Further, the backlight device 12 includes an LED substrate (light source substrate) 18 on which the LEDs 17 are provided, and a part of the chassis 22 is opposed to the light incident surface 19 b that is an end surface of the light guide plate 19. The board mounting portion 37 has a surface and the LED board 18 is mounted on the opposite surface. In this way, the liquid crystal panel 11 and the light guide plate 19 are held in a state of being sandwiched between the chassis 22 and the frame 13 in a state of being overlapped with each other. Therefore, the light guide plate 19 may be displaced in the plate thickness direction depending on the holding force of the chassis 22 and the frame 13. In that respect, as described above, a part of the chassis 22 has a facing surface that is opposed to the light incident surface 19 b that is the end surface of the light guide plate 19, and the board mounting portion 37 to which the LED substrate 18 is attached. Therefore, compared with the case where the LED substrate 18 is attached to a member different from the chassis 22 and the member is attached to the substrate attachment portion 37, the LED substrate 18 and the substrate attachment portion 37 are disposed between them. Possible assembly errors can be reduced. In addition, the LED substrate 18 is directly attached to the surface of the substrate attachment portion 37 that faces the light incident surface 19b that is the end surface of the light guide plate 19, whereby the LED 17 is attached to the light incident surface 19b that is the end surface of the light guide plate 19. Positioning can be easily performed in the direction along the light incident surface 19b which is the same end surface while being arranged in an opposing manner. Thereby, the position shift which can arise between the light-incidence surface 19b which is the end surface about the direction along the light-incidence surface 19b which is the end surface of the light-guide plate 19, and LED17 can be reduced. Therefore, it is possible to improve the incident efficiency of light incident from the LED 17 to the light incident surface 19b which is the end surface of the light guide plate 19, and to uneven brightness in the light emitted from the light output surface 19a which is the plate surface of the light guide plate 19. Is less likely to occur.
 また、シャーシ22は、導光板19を液晶パネル11側とは反対側から支持する導光板支持部22a1と、導光板支持部22a1よりも導光板19側とは反対側に膨出する形で設けられるとともに、基板取付部37に取り付けられているLED基板18を収容し且つ基板取付部37に連なる基板収容部22a2とを有しているのに対し、基板収容部22a2における外面に接する形で取り付けられる放熱部材23が備えられている。このようにすれば、導光板支持部22a1よりも導光板19側とは反対側に膨出する基板収容部22a2によって基板取付部37に取り付けられるLED基板18の収容スペースを十分に確保することができる。これにより、LED基板18に設けられるLED17における導光板19の板厚方向についての寸法に関する設計上の自由度を高めることができるから、LED17から導光板19の端面である光入射面19bに入射する光の入射効率を最適化する上で有用となる。しかも、LED17が発光するのに伴って生じる熱は、LED基板18及び基板取付部37から基板収容部22a2へと伝達されてから、導光板支持部22a1へと伝達されるとともに基板収容部22a2の外面に接する形で取り付けられる放熱部材23へと伝達される。上記したようにLED基板18は、基板取付部37に対して直接取り付けられているため、仮に放熱部材を介して基板取付部37に取り付けられたものに比べると、LED17からの熱が放熱され難くなっている。その点、上記したように基板収容部22a2の外面に接する形で放熱部材23を取り付けるようにすれば、LED基板18と基板取付部37との間に生じ得る組み付け誤差を小さくしつつも、放熱性能を十分に補うことができる。 The chassis 22 is provided in such a manner that the light guide plate 19 supports the light guide plate 19 from the side opposite to the liquid crystal panel 11 and bulges to the side opposite to the light guide plate 19 from the light guide plate support 22a1. In addition, the LED board 18 mounted on the board mounting part 37 is housed and has a board housing part 22a2 connected to the board mounting part 37, while being attached in contact with the outer surface of the board housing part 22a2. The heat dissipation member 23 is provided. In this way, it is possible to sufficiently secure an accommodation space for the LED substrate 18 attached to the substrate attachment portion 37 by the substrate accommodation portion 22a2 that bulges to the opposite side of the light guide plate 19 side from the light guide plate support portion 22a1. it can. Thereby, since the freedom degree in the design regarding the dimension about the plate | board thickness direction of the light guide plate 19 in LED17 provided in LED board 18 can be raised, it injects into the light-incidence surface 19b which is the end surface of the light guide plate 19 from LED17. This is useful for optimizing the light incident efficiency. Moreover, the heat generated as the LED 17 emits light is transmitted from the LED substrate 18 and the substrate mounting portion 37 to the substrate housing portion 22a2, and then to the light guide plate support portion 22a1, and at the same time, the substrate housing portion 22a2. The heat is transmitted to the heat radiating member 23 attached in contact with the outer surface. As described above, since the LED substrate 18 is directly attached to the substrate attachment portion 37, heat from the LED 17 is less likely to be dissipated compared to a case where the LED substrate 18 is attached to the substrate attachment portion 37 via a heat dissipation member. It has become. In that respect, if the heat radiating member 23 is attached so as to be in contact with the outer surface of the substrate housing portion 22a2, as described above, heat radiation can be reduced while reducing an assembly error that may occur between the LED substrate 18 and the substrate attachment portion 37. The performance can be fully supplemented.
 また、放熱部材23は、基板収容部22a2の外面に並行し且つ同外面に接する第1放熱部23aと、第1放熱部23aに連なるとともに基板取付部37に並行する第2放熱部23bとを有しており、フレーム13は、液晶パネル11を導光板19側とは反対側から押さえる枠状部(フレーム基部)13aと、枠状部13aから第2放熱部23bに沿って突出するとともに第2放熱部23bに接する形で取り付けられる取付板部13cとを有しており、さらには挿通孔32は、基板取付部37と取付板部13cとの間に位置して配されているのに対し、放熱部材23には、挿通孔32に連通することでフレキシブル基板27を通す連通切欠部33が形成されている。このようにすれば、基板収容部22a2からの熱は、放熱部材23における第1放熱部23aから第2放熱部23bへと伝達された後、第2放熱部23bに接する形で取り付けられるフレーム13の取付板部13cへと伝達される。これにより、フレーム13を利用してLED17の放熱を図ることができるから、放熱性能に一層優れる。しかも、シャーシ22の基板収容部22a2とフレーム13の取付板部13cとに取り付けられる放熱部材23には、取付板部13cと基板取付部37との間に位置して配される挿通孔32に連通する連通切欠部33が形成されているから、フレキシブル基板27を挿通孔32及び連通切欠部33に通してタッチパネル駆動回路基板26に接続することができる。 The heat radiating member 23 includes a first heat radiating portion 23 a that is parallel to and in contact with the outer surface of the substrate housing portion 22 a 2, and a second heat radiating portion 23 b that is continuous with the first heat radiating portion 23 a and is parallel to the substrate mounting portion 37. The frame 13 has a frame-like part (frame base part) 13a that holds the liquid crystal panel 11 from the side opposite to the light guide plate 19 side, and projects from the frame-like part 13a along the second heat radiating part 23b. 2 has a mounting plate portion 13c attached in contact with the heat radiating portion 23b, and the insertion hole 32 is disposed between the board mounting portion 37 and the mounting plate portion 13c. On the other hand, the heat radiating member 23 is formed with a communication notch 33 through which the flexible substrate 27 is passed by communicating with the insertion hole 32. In this way, the heat from the substrate housing portion 22a2 is transmitted from the first heat radiating portion 23a to the second heat radiating portion 23b in the heat radiating member 23, and then attached to the second heat radiating portion 23b. To the mounting plate portion 13c. Thereby, since heat dissipation of LED17 can be aimed at using the flame | frame 13, it is further excellent in heat dissipation performance. In addition, the heat dissipation member 23 attached to the board accommodating portion 22a2 of the chassis 22 and the attachment plate portion 13c of the frame 13 has an insertion hole 32 disposed between the attachment plate portion 13c and the substrate attachment portion 37. Since the communication cutout portion 33 that is in communication is formed, the flexible substrate 27 can be connected to the touch panel drive circuit substrate 26 through the insertion hole 32 and the communication cutout portion 33.
 また、放熱部材23の第2放熱部23bと基板取付部37との間には、隙間C1が有されており、挿通孔32は、隙間C1に臨む位置に配されている。このようにすれば、挿通孔32に通されたフレキシブル基板27は、放熱部材23の連通切欠部33に加えて、第2放熱部23bと基板取付部37との間に有される隙間C1に通されることで、タッチパネル駆動回路基板26へとより容易に引き回される。 Further, a gap C1 is provided between the second heat radiating portion 23b of the heat radiating member 23 and the board mounting portion 37, and the insertion hole 32 is disposed at a position facing the gap C1. In this way, the flexible substrate 27 passed through the insertion hole 32 is formed in the gap C <b> 1 between the second heat radiating portion 23 b and the substrate mounting portion 37 in addition to the communication cutout portion 33 of the heat radiating member 23. By being passed, it is more easily routed to the touch panel drive circuit board 26.
 また、表示パネルは、一対の基板間11a,11bに液晶を封入してなる液晶パネル11とされる。このような表示装置は液晶表示装置10として、種々の用途、例えばタブレット型パソコンや携帯型情報端末のディスプレイ等に好適に適用できる。 The display panel is a liquid crystal panel 11 in which liquid crystal is sealed between a pair of substrates 11a and 11b.

<Embodiment 2>
A second embodiment of the present invention will be described with reference to FIG. In this Embodiment 2, what changed the formation range of the penetration hole 132 is shown. In addition, the overlapping description about the same structure, an effect | action, and effect as above-mentioned Embodiment 1 is abbreviate | omitted.
 本実施形態に係る挿通孔132は、図12に示すように、枠状部113aのうち段差GPよりも内側の内周部分113a1にのみ形成されており、上記した実施形態1に記載した挿通孔32(図8を参照)よりも形成範囲が狭くなっている。挿通孔132におけるY軸方向についての形成範囲は、放熱部材123の第2放熱部123bと基板取付部137との間に有される隙間C1の間隔とほぼ同じ程度とされる。このように挿通孔132の形成範囲を制限することで、挿通孔132に対して表側から挿通したフレキシブル基板127を、上記隙間C1へと容易に導くことができる。 As shown in FIG. 12, the insertion hole 132 according to the present embodiment is formed only in the inner peripheral portion 113a1 inside the step GP in the frame-shaped portion 113a, and the insertion hole described in the first embodiment described above. The forming range is narrower than 32 (see FIG. 8). The formation range in the Y-axis direction in the insertion hole 132 is approximately the same as the gap C1 provided between the second heat radiating portion 123b of the heat radiating member 123 and the board mounting portion 137. By limiting the formation range of the insertion hole 132 in this way, the flexible substrate 127 inserted from the front side into the insertion hole 132 can be easily guided to the gap C1.
 <実施形態3>
 本発明の実施形態3を図13から図15によって説明する。この実施形態3では、挿通孔232の孔縁にテーパ面42を形成したものを示す。なお、上記した実施形態2と同様の構造、作用及び効果について重複する説明は省略する。
<Embodiment 3>
A third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, a taper surface 42 is formed at the hole edge of the insertion hole 232. In addition, the overlapping description about the same structure, an effect | action, and effect as above-mentioned Embodiment 2 is abbreviate | omitted.
 本実施形態に係る枠状部213aに形成された挿通孔232のうち裏側の孔縁には、図13に示すように、テーパ面42が形成されている。テーパ面42は、挿通孔232における裏側への開口幅が開口端に近づくに連れて広がるような勾配を有している。これにより、フレキシブル基板227を挿通孔232に通す際に裏側の孔縁がフレキシブル基板227に引っ掛かり難くなり、フレキシブル基板227に傷が付くといった事態が生じ難くなっている。 As shown in FIG. 13, a tapered surface 42 is formed at the hole edge on the back side of the insertion hole 232 formed in the frame-like portion 213a according to the present embodiment. The tapered surface 42 has a gradient such that the opening width to the back side of the insertion hole 232 increases as it approaches the opening end. As a result, when the flexible board 227 is passed through the insertion hole 232, the hole edge on the back side is hardly caught by the flexible board 227, and it is difficult for the situation that the flexible board 227 is damaged.
 続いて、フレーム213を製造する際のテーパ面42の形成方法について説明する。フレーム213をプレス加工により成形する際に、枠状部213aを部分的にZ軸方向に沿って表側から裏側に向けて打ち抜くことで、挿通孔232が形成される。このとき、挿通孔232のうち、打ち抜き方向の前側に位置する裏側の孔縁には、図14に示すように、鋭利なバリBUが裏側に突き出すように形成される場合がある。このため、挿通孔232が形成された後、その裏側の孔縁に対して挿通孔232よりも幅広な押し具PTを裏側から表側へ向けて押し当てる、面押し加工を行う。すると、挿通孔232における裏側の孔縁には、図15に示すように、押し具PTの先端面に形成されたテーパ面が転写されてテーパ面42が形成される。 Subsequently, a method of forming the tapered surface 42 when manufacturing the frame 213 will be described. When the frame 213 is formed by press working, the insertion hole 232 is formed by punching the frame-shaped portion 213a partially from the front side to the back side along the Z-axis direction. At this time, as shown in FIG. 14, a sharp burr BU may be formed on the back side edge of the insertion hole 232 located on the front side in the punching direction so as to protrude to the back side. For this reason, after the insertion hole 232 is formed, a surface pressing process is performed in which a pressing tool PT wider than the insertion hole 232 is pressed against the hole edge on the back side from the back side to the front side. Then, as shown in FIG. 15, the tapered surface formed on the distal end surface of the pressing tool PT is transferred to the hole edge on the back side of the insertion hole 232 to form the tapered surface 42.
 以上説明したように本実施形態によれば、フレーム213における挿通孔232の孔縁には、テーパ面42が形成されている。このようにすれば、フレキシブル基板227を挿通孔232に通す際に、挿通孔232の孔縁によってフレキシブル基板227が損傷を受ける事態が生じ難くなる。 As described above, according to the present embodiment, the tapered surface 42 is formed at the hole edge of the insertion hole 232 in the frame 213. In this way, when the flexible board 227 is passed through the insertion hole 232, it is difficult for the flexible board 227 to be damaged by the hole edge of the insertion hole 232.
 <実施形態4>
 本発明の実施形態4を図16によって説明する。この実施形態4では、上記した実施形態2からテーパ面342の形成位置及び挿通孔332の形成方法を変更したものを示す。なお、上記した実施形態2と同様の構造、作用及び効果について重複する説明は省略する。
<Embodiment 4>
A fourth embodiment of the present invention will be described with reference to FIG. This Embodiment 4 shows what changed the formation position of the taper surface 342 and the formation method of the penetration hole 332 from above-mentioned Embodiment 2. FIG. In addition, the overlapping description about the same structure, an effect | action, and effect as above-mentioned Embodiment 2 is abbreviate | omitted.
 本実施形態に係るテーパ面342は、図16に示すように、枠状部313aに形成された挿通孔332における表側の孔縁に形成されている。このようにすれば、挿通孔332に対して表側からフレキシブル基板327を通す際に、表側の孔縁に形成されたテーパ面342によってフレキシブル基板327を円滑に裏側へと案内することができ、作業性に優れる。挿通孔332及びテーパ面342は、共に枠状部313aに部分的に切削加工を施すことで形成されている。 As shown in FIG. 16, the tapered surface 342 according to the present embodiment is formed on the front edge of the insertion hole 332 formed in the frame-like portion 313a. In this way, when the flexible board 327 is passed from the front side to the insertion hole 332, the flexible board 327 can be smoothly guided to the back side by the tapered surface 342 formed at the hole edge on the front side. Excellent in properties. Both the insertion hole 332 and the tapered surface 342 are formed by partially cutting the frame-like portion 313a.

<Embodiment 5>
Embodiment 5 of the present invention will be described with reference to FIG. In the fifth embodiment, the position of the mounting plate portion 413c of the frame 413 is changed.

 本実施形態に係る取付板部413cは、図17に示すように、その内側を向いた板面が基板取付部437における外側の板面との間に隙間を有さず、同板面に接する形で配されている。つまり、取付板部413cは、放熱部材423の第2放熱部423bと基板取付部437との間に挟み込まれる形で配されている。このような構成とすれば、LED417から発せられた熱が、基板取付部437から直接取付板部413cへと伝達されるとともに、基板収容部422a2及び放熱部材423を介して取付板部413cへと伝達されることで放熱が図られる。上記したように取付板部413cの位置を変更するのに伴い、挿通孔432の配置も変更されており、具体的には、挿通孔432は、枠状部413aにおいて取付板部413cに対して外側に隣り合う位置に配されている。放熱部材423のうち、挿通孔432と平面に視て重畳する部分(第2放熱部423bを含む)には、挿通孔432に連通する連通切欠部433が形成されている。 As shown in FIG. 17, the mounting plate portion 413 c according to the present embodiment does not have a gap between the plate surface facing inward and the outer plate surface of the substrate mounting portion 437, and is in contact with the plate surface. It is arranged in a form. That is, the mounting plate portion 413 c is arranged in a form sandwiched between the second heat radiating portion 423 b of the heat radiating member 423 and the board mounting portion 437. With such a configuration, the heat generated from the LED 417 is directly transmitted from the board mounting portion 437 to the mounting plate portion 413c, and to the mounting plate portion 413c via the board housing portion 422a2 and the heat dissipation member 423. Heat is dissipated by being transmitted. As described above, as the position of the mounting plate portion 413c is changed, the arrangement of the insertion holes 432 is also changed. Specifically, the insertion holes 432 are arranged in the frame-shaped portion 413a with respect to the mounting plate portion 413c. It is arranged at a position adjacent to the outside. A communication notch 433 that communicates with the insertion hole 432 is formed in a portion of the heat dissipation member 423 that overlaps with the insertion hole 432 in a plan view (including the second heat dissipation part 423b).

 本実施形態に係る連通切欠部533は、図18に示すように、放熱部材523における第1放熱部523aを貫通する孔状に形成されている。連通切欠部533は、第1放熱部523aのうち第2放熱部523bに隣接する位置に形成されており、第2放熱部523bと基板取付部537との間に有される隙間C1に臨む配置とされている。これにより、挿通孔532に通されたフレキシブル基板527は、上記隙間C1に通された後に連通切欠部533に通されることで、裏側のタッチパネル駆動回路基板526へと接続されている。 The communication notch 533 according to the present embodiment is formed in a hole shape penetrating the first heat radiating portion 523a in the heat radiating member 523, as shown in FIG. The communication notch 533 is formed at a position adjacent to the second heat radiating portion 523b in the first heat radiating portion 523a and is disposed so as to face the gap C1 provided between the second heat radiating portion 523b and the board mounting portion 537. It is said that. Thus, the flexible substrate 527 passed through the insertion hole 532 is connected to the touch panel drive circuit substrate 526 on the back side by passing through the gap C1 and then passing through the communication cutout portion 533.
