Definitions
- the present invention relates to a display device.
- Display devices equipped with a display panel such as a liquid crystal panel are used in portable information terminal devices such as mobile phones, smartphones and PDAs, and electronic devices such as computers and television receivers.
- a function of displaying a stereoscopic image called a “parallax barrier method” using the difference between the left and right eyes, that is, the characteristics of the human eye that senses a stereoscopic image from binocular parallax. What you have is known.
- a display device having a function of displaying such a three-dimensional image a device described in Patent Document 1 below is known.
- a barrier light shielding layer is provided for a liquid crystal panel that displays an image.
- the parallax barrier panel which has this is the structure which bonded together with the adhesive material.
- the barrier light-shielding layer of the parallax barrier panel is fixedly provided, and the stereoscopic image is always displayed.
- a switch liquid crystal panel having a liquid crystal layer sandwiched between a pair of substrates may be used as a parallax barrier panel.
- a light shielding wiring portion made of a light shielding metal material is provided in a frame portion of the switch liquid crystal panel, that is, a portion overlapping the non-display area of the display liquid crystal panel in plan view.
- the switch liquid crystal panel is bonded to the liquid crystal panel for display, for example, when a photocurable adhesive that is cured by light of a specific wavelength such as ultraviolet rays is used as the adhesive, the switch is cured. For this reason, the light cannot pass through the light-shielding wiring part, so that the curing of the photocurable adhesive material may be partially insufficient. In such a case, the holding power of the liquid crystal panel and the switch liquid crystal panel is insufficient, and there is a possibility that peeling or the like may occur.
- the present invention has been completed based on the above circumstances, and an object thereof is to sufficiently cure a photocurable adhesive.
- the display device of the present invention is a display panel having a display area capable of displaying an image and a non-display area surrounding the display area, and is bonded to the display panel.
- a functional panel having a display overlapping region to be superimposed and a non-display overlapping region overlapping with the non-display region in a plan view, and interposed between the display panel and the functional panel and cured by light irradiation.
- transmits the said light while being formed by notching the said light-shielding wiring part partially are provided.
- a transparent electrode portion made of a transparent conductive material is disposed in a display overlapping region that overlaps with the display region of the display panel in a plan view.
- a light shielding wiring portion made of a light shielding metal material is disposed in a non-display overlapping region that overlaps the non-display region in plan view.
- the photocurable adhesive Accordingly, a sufficient amount of light for curing the photocurable adhesive can be applied to the photocurable adhesive in the display overlapping area of the functional panel, but the light shielding wiring portion in the nondisplay overlapping area. Therefore, the amount irradiated to the photocurable adhesive tends to be insufficient.
- the light-shielding wiring portion is partially cut out to form a cut-out light-transmitting portion that transmits light, so that the light-curing adhesive is irradiated by the area of the cut-out light-transmitting portion.
- the amount of light emitted can be increased.
- the photo-curable adhesive can be sufficiently cured even in the non-display overlapping region of the functional panel, and the bonded display panel and functional panel can be held with sufficient holding power. The effect of can be obtained.
- the light shielding wiring part includes a potential supply wiring part that is connected to the light transmitting electrode part and can supply a potential to the light transmitting electrode part.
- the potential supply wiring part included in the light shielding wiring part is made of a light shielding metal material, the wiring resistance is lower than that of the light transmitting conductive material constituting the light transmitting electrode part.
- the uniformity is also high. Therefore, as compared with the case where the potential supply wiring portion is made of a translucent conductive material, the potential can be stably supplied from the potential supply wiring portion to the light transmitting electrode portion.
- At least one of the translucent electrode portion disposed in the display overlap region and the potential supply wiring portion disposed in the non-display overlap region extends toward the other region side.
- an extension connection part connected to the other party is provided.
- the extension connection portion extending toward the partner region is connected to the partner, so that the translucent electrode portion disposed in the display overlap region and the non-display overlap region are disposed.
- the potential supply wiring portion can be connected.
- the extension connection portion is provided in the light-transmitting electrode portion and extends toward the non-display overlapping region to be connected to the potential supply wiring portion. In this way, if an extension connection part is provided on the potential supply wiring part side, it is displayed in the display area as compared with the case where the light shielding object is present in the display overlapping area of the functional panel. Display quality of the image can be increased.
- a flexible substrate connected to an external circuit is connected to the functional panel, and at the end of the potential supply wiring portion opposite to the side connected to the light transmitting electrode portion.
- the terminal part connected to the said flexible substrate is formed. In this way, the potential supplied from the external circuit can be supplied to the transparent electrode portion via the flexible substrate and the potential supply wiring portion.
- the light shielding wiring portion includes a ground wiring portion connected to the ground, and the ground wiring portion has a substantially annular shape surrounding the potential supply wiring portion in addition to the display overlapping region. According to this configuration, the potential is supplied to the translucent electrode portion and the translucent electrode portion arranged in the display overlapping region by surrounding the potential supply wiring portion in addition to the display overlapping region by the ground wiring portion connected to the ground.
- the potential supply wiring portion can be kept in a shield state. Thereby, the potential supply to the translucent electrode part can be performed more stably.
- the light-shielding wiring portion includes a first light-shielding wiring portion and a second light-shielding wiring portion that are formed on different surfaces of the functional panel and at least partially overlap each other when seen in a plane.
- the notched light transmitting portion includes a first notched light transmitting portion formed in the first light shielding wiring portion and a second notched light transmitting portion formed in the second light shielding wiring portion.
- the first notch light transmitting part and the second notch light transmitting part are arranged so as to overlap each other in a plan view.
- the functional panel is a parallax barrier panel capable of separating an image displayed on the display panel by parallax. In this way, by separating the image displayed on the display panel by the parallax barrier panel based on the parallax, the user of the display device can view the stereoscopic image.
- the parallax barrier panel includes a pair of substrates facing each other and a liquid crystal sealed between the pair of substrates, and the plate surface on the liquid crystal side of the pair of substrates includes:
- the translucent electrode portions are formed so as to be opposed to each other, and by controlling the voltage value between the translucent electrode portions that form a pair, a plurality of barrier portions that block light and between the adjacent barrier portions And a barrier opening through which light can be transmitted.
- the observation angle at which the image displayed on the display panel can be observed through the barrier opening arranged between the adjacent barrier portions is specified.
- the image can be separated by parallax.
- by controlling the voltage value between the pair of transparent electrode portions it is possible to select whether to form the barrier portion and the barrier opening portion in the parallax barrier panel.
- the display can be switched.
- the translucent electrode portion is formed on a plate surface opposite to the liquid crystal side of any one of the pair of substrates, and a position input by a user of the display device
- the touch panel pattern for detecting the image is configured. In this way, the parallax barrier panel can have a touch panel function.
- the functional panel is a touch panel that constitutes a touch panel pattern in which the transparent electrode portion detects a position input by a user of the display device. If it does in this way, the position which the user input by the touch panel pattern comprised by the translucent electrode part can be detected.
- a plurality of the notched light transmitting portions are arranged in parallel in the length direction and the width direction of the light shielding wiring portion. In this way, since the light shielding wiring portion has a substantially mesh shape when seen in a plane, problems such as disconnection hardly occur.
- the plurality of cutout light transmitting portions are equal in size and arrangement pitch. If it does in this way, light can be irradiated more uniformly with respect to a photocurable adhesive material through a some notch transparent part.
- the cutout light-transmitting portion extends in parallel with the length direction of the light shielding wiring portion. In this way, since the light shielding wiring portion has a substantially striped shape when viewed in a plane, the area of the cut-out light transmitting portion is smaller than when the light shielding wiring portion is formed in a mesh shape when viewed in a plane. It can be made larger, and the amount of light applied to the photocurable adhesive can be increased.
- the display panel is a liquid crystal panel in which liquid crystal is sealed between a pair of substrates, and includes a lighting device capable of irradiating the liquid crystal panel with light. If it does in this way, an image can be displayed on a liquid crystal panel with the light irradiated from an illuminating device.
- a display device can be applied as a liquid crystal display device to various electronic devices such as a portable information terminal, a mobile phone, a notebook computer, and a portable game machine.
- the photocurable adhesive can be sufficiently cured.

Abstract
Description
上記した特許文献1に記載されたものでは、視差バリアパネルのバリア遮光層が固定的に設けられていて、常時立体画像を表示する構成とされる。その一方で、立体画像の表示と、平面画像の表示とを切り替えるため、視差バリアパネルとして、一対の基板間に液晶層を挟み込んだ構成のスイッチ液晶パネルを用いる場合がある。このスイッチ液晶パネルを用いるに際しては、スイッチ液晶パネルの額縁部分、つまり表示用の液晶パネルの非表示領域と平面視重畳する部分に遮光性金属材料からなる遮光配線部が設けられる場合がある。その上で、このスイッチ液晶パネルを、表示用の液晶パネルに対して貼り合わせるに際して、例えば接着材として紫外線などの特定の波長の光によって硬化する光硬化性接着材を用いた場合には、硬化のための光が遮光配線部を透過できず、そのため光硬化性接着材の硬化が部分的に不十分となるおそれがあった。そうなると、液晶パネル及びスイッチ液晶パネルの保持力が不十分となって例えば剥落などが生じるおそれがあった。また、上記のような剥落が生じずとも、光硬化性接着材に半硬化部分や未硬化部分が生じる可能性があり、そうなると液晶パネルとスイッチ液晶パネルとが部分的に剥離し、その剥離部の界面にて光が乱反射することで表示品位が低下するおそれがある。また、光硬化性接着材に半硬化部分や未硬化部分が生じると、光硬化性接着材の膜厚が不均一なものとなるため、やはり表示品位を低下させる可能性がある。また、液晶パネル及びスイッチ液晶パネルの外縁部において光硬化性接着材に未硬化部分が生じると、液体状の光硬化性接着材が外部の漏れ出すおそれがある。
本発明の表示装置は、画像を表示可能な表示領域、及び前記表示領域を取り囲む非表示領域を有する表示パネルと、前記表示パネルに貼り合わせられるものであって、前記表示領域と平面に視て重畳する表示重畳領域、及び前記非表示領域と平面に視て重畳する非表示重畳領域を有する機能性パネルと、前記表示パネルと前記機能性パネルとの間に介在するとともに光の照射により硬化される光硬化性接着材と、前記機能性パネルにおける前記表示重畳領域に配されるとともに透光性導電材料からなる透光電極部と、前記機能性パネルにおける前記非表示重畳領域に配されるとともに遮光性金属材料からなる遮光配線部と、前記遮光配線部を部分的に切り欠くことで形成されるとともに前記光を透過する切欠透光部とを備える。
(1)前記遮光配線部には、前記透光電極部に対して接続されることで、前記透光電極部に電位を供給可能な電位供給配線部が含まれている。このようにすれば、遮光配線部に含まれる電位供給配線部は、遮光性金属材料からなるものであるから、透光電極部を構成する透光性導電材料に比べると、配線抵抗が低く且つその均一性も高いものとされる。従って、仮に電位供給配線部を透光性導電材料から構成した場合に比べると、電位供給配線部から透光電極部に対して電位を安定的に供給することができる。
本発明によれば、光硬化性接着材を十分に硬化させることができる。
本発明の実施形態1を図1から図23によって説明する。本実施形態では、液晶表示装置(表示装置)10について例示する。なお、各図面の一部にはX軸、Y軸及びZ軸を示しており、各軸方向が各図面で示した方向となるように描かれている。また、上下方向については、図1を基準とし、且つ同図上側を表側とするとともに同図下側を裏側とする。
本発明の実施形態2を図24によって説明する。この実施形態2では、切欠透光部135,136の形状を変更したものを示す。なお、上記した実施形態1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。
本発明の実施形態3を図25によって説明する。この実施形態3では、切欠透光部235,236の形状を変更したものを示す。なお、上記した実施形態1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。
本発明の実施形態4を図26または図27によって説明する。この実施形態4では、切欠透光部335,336の形状を変更したものを示す。なお、上記した実施形態1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。
本発明の実施形態5を図28によって説明する。この実施形態5では、機能性パネル412の構成を変更したものを示す。なお、上記した実施形態1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。
本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれる。
(1)上記した実施形態1~4以外にも、切欠透光部の形状は適宜に変更可能である。例えば、図29に示すように、平面に視て正方形をなす切欠透光部35‐1(36‐1)を形成するようにしてもよい。
