[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device and an electronic apparatus, and more particularly to a structure of a liquid crystal display panel in which a region outside a display area is reduced as much as possible in miniaturizing the liquid crystal display device.

[0002]

2. Description of the Related Art In recent years, a liquid crystal display device has been widely used as a means for displaying various information in electronic devices such as a notebook personal computer, a mobile phone, a wristwatch and the like. Usually, in this type of liquid crystal display device, particularly a liquid crystal display device called a simple matrix type, a liquid crystal is sealed in a space sandwiched between two transparent substrates, and a stripe shape orthogonal to each other is formed on a facing surface of each transparent substrate. A transparent electrode is formed. In this liquid crystal display device, a portion where a transparent electrode on two substrates intersects serves as a pixel, and a method of driving the liquid crystal of each pixel from the outside is adopted. In order to drive the liquid crystal from the outside, an input terminal is provided in a region outside a region (hereinafter, referred to as a display region) on which a large number of pixels are formed on a transparent substrate, and the input terminal and each transparent electrode are routed and wired. And an input terminal is connected to a driving IC or the like. In the conventional structure, 2
Since the transparent electrodes on the transparent electrodes are provided in directions orthogonal to each other, input terminals for supplying a drive signal to each transparent electrode are also provided in the extending direction of each transparent electrode.

FIG. 10 is a schematic diagram of a conventional general liquid crystal display panel. In the liquid crystal display panel 100, a liquid crystal (not shown) is sealed between an upper substrate 101 and a lower substrate 102 made of two transparent substrates.
Striped transparent electrodes (not shown) orthogonal to each other are formed on the opposing surfaces of 01 and 102. Both substrates 10
A portion where the transparent electrodes 1 and 102 overlap is a pixel 103, and a portion where a number of pixels 103 are arranged is a display region 104. The lower substrate 102 is disposed so as to protrude outward from one side 101a of the upper substrate 101,
At the protruding portion, a lead wiring 105 extending from the transparent electrode of the lower substrate 102 is provided.
5 is connected to the driving IC 106 as an input terminal. Similarly, the upper substrate 101 is disposed so as to protrude from one side 102 a of the lower substrate 102, and the protruding portion is provided with a wiring 107 extending from the transparent electrode of the upper substrate 101. One end of 107 is connected to the driving IC 108 as an input terminal. In the case of a small-sized liquid crystal display panel, one drive IC may be enough to drive the electrodes of the upper and lower substrates, but two or more drive ICs are required for a scale of about 200 × 200 pixels or more. And the above configuration has to be adopted.

[0004]

The above-mentioned conventional liquid crystal display panel has the following problems.

As described above, in a conventional liquid crystal display panel, a driving circuit portion in which a wiring and a driving IC are arranged is provided in a region outside two adjacent sides of a rectangular display region. . When the liquid crystal display panel of this configuration is accommodated in a frame and completed as a liquid crystal display device, the outermost periphery when the liquid crystal display panel is viewed in a plan view is fixed by covering it with a frame. A frame-shaped area outside the display area, a so-called frame area, becomes large, and the area occupied by the entire liquid crystal display device (the area of W × L in FIG. 10) becomes large. In addition, the area adjacent to the two drive circuit units is a useless space that is not used in the frame, and the use efficiency of the internal space of the frame is deteriorated.

Further, in this configuration, since a driving IC is mounted on each of the upper substrate and the lower substrate, a flexible printed circuit (Flexible Printed Circuit) for inputting a driving signal to be supplied to the driving IC is provided. , Below, F
(Hereinafter abbreviated as PC) must be connected to each substrate, and there is a problem that it is troublesome to handle the FPC inside the frame.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and a liquid crystal display device capable of reducing the size by reducing the area of a frame region of a liquid crystal display panel, and using the same. The purpose of the present invention is to provide electronic equipment.

[0008]

In order to achieve the above object, in a liquid crystal display device of the present invention, a liquid crystal is sealed between a pair of substrates facing each other, and the liquid crystal is provided on each of the surfaces of the substrates facing each other. A plurality of striped electrodes arranged orthogonally to each other, wherein a plurality of first electrodes on one of the pair of substrates are disposed below a plurality of first electrodes via an insulating film. A first wiring is provided, each of the plurality of first electrodes is electrically connected to each of the plurality of first wirings, and one end of the first wiring is used as a drive input terminal. A plurality of second routing wirings extending toward one side of the one substrate and not electrically connected to the first routing wiring are provided on the one substrate, and one end of the second routing wiring is driven. Input terminal And extending toward the same side as the side on which one end of the first routing wiring extends, and each of the plurality of second electrodes on the other of the pair of substrates is connected to the plurality of second routing wirings. It is characterized by being electrically connected.

The first routing wiring extends toward the same side as the side on which one end extends. With this configuration, the planar positional relationship between the one substrate and the other substrate is different from the conventional case in which the one substrate and the other substrate are arranged so as to protrude outside two adjacent sides of the display area. Instead, it is sufficient to arrange only one of the substrates so as to protrude outside one side of the display area. Therefore, according to the liquid crystal display device of the present invention, the area of the frame region outside the display region can be reduced as compared with the conventional one, and the size can be reduced. Also, when the liquid crystal display device is housed inside a frame or the like, no unused space is left in the frame.

In the case of the liquid crystal display device of the present invention, one end of the first wiring and one end of the second wiring extend toward one side of one of the pair of substrates as a driving input terminal. Therefore, a first driving element for driving a plurality of first electrodes on one substrate is mounted on one end of the first routing wiring, and a plurality of first driving elements on the other substrate are mounted on one end of the second routing wiring. It is preferable that a second driving element for driving the two electrodes is mounted.

With this configuration, two driving elements can be combined on one side of one of the substrates, and the operation of mounting the driving elements can be easily performed.

Further, it is preferable that one common printed wiring board for inputting signals to be supplied to each of the first driving element and the second driving element is connected to one substrate.

Of course, one printed wiring board may be connected to each of the first driving element and the second driving element.
When one common printed wiring board is connected to the first driving element and the second driving element, the layout of the printed wiring board becomes easy when this liquid crystal display device is mounted on an electronic device, and the printed wiring board is easily printed. The space occupied by the board can be reduced. Of course, the amount of printed wiring boards used is reduced by half.

Various methods are conceivable for the electrical connection between the second electrode on the other substrate and the second routing wiring on the one substrate. For example, each second electrode and each second routing wiring are electrically connected. Can be electrically connected via a conductive material inserted inside the sealing material.

With this configuration, electrical connection between the two substrates can be easily realized without using another connecting member.

In the liquid crystal display device of the present invention, both the first wiring for driving the first electrode and the second wiring for driving the second electrode are provided on one substrate. Must not be short-circuited. As a specific method of avoiding a short circuit, for example, it is desirable to provide a configuration in which the first wiring is provided below the insulating film and the second wiring is provided above the insulating film. With such a two-layer structure with the insulating film interposed therebetween, the first routing wiring and the second routing wiring can be arranged so as to overlap in a plane, so that the occupied area of the wiring portion can be reduced. .

An electronic apparatus according to the present invention includes the above-described liquid crystal display device according to the present invention.

According to this configuration, the provision of the liquid crystal display device of the present invention makes it possible to reduce the size of electronic equipment.

A display area 8 is formed by arranging 00 pixels in a rectangular shape.

The planar shapes of the lower substrate 3 and the upper substrate 2 are both rectangular, but the lower substrate 3 is larger on one side than the upper substrate 2, and the lower substrate 3 is one side of the upper substrate 2. 2
It is arranged so that it may protrude outside from a. The protruding portion of the lower substrate 3 constitutes the drive circuit unit 9 of the present liquid crystal display device 1, and the scan electrode side drive IC 10 (first drive element) and the signal electrode side drive IC 11 (second drive element) Are mounted. Further, at one corner of the drive circuit section 9 on the lower substrate 3, these two drive I

As shown in FIG. 2, a large number of signal electrodes 7 extending in one direction are formed on a transparent substrate 13 constituting the upper substrate 2. A region 15 indicated by a two-dot chain line indicates a region where the sealing material 4 is arranged.
One end 7a extends to such an extent that it comes into contact with the edge of the sealing material arrangement region 15. On the other hand, the other end 7b of each signal electrode 7 extends to a position overlapping with the sealing material arrangement area 15, and at this position, a signal electrode lead-out wiring 17 (second lead-out wiring) on the lower substrate 3 described later. It is designed to be electrically connected to.

Next, the configuration of the lower substrate 3 will be described. The lower substrate 3 has a two-layer wiring structure. FIG. 3 shows a configuration of only the lower layer, and FIG. 4 shows a configuration of only the upper layer. Reference numeral 5 denotes the entire configuration of the lower substrate 3. FIG.

As shown in FIG. 6, an acrylic resin is provided on the scanning electrode lead-out wiring 16 to a position that covers most of the scan electrode lead-out wiring 16 and exposes the scan electrode side driving IC 10. An insulating film 20 of about 5 μm in thickness is formed. 1 and 3 to 5,
The boundary indicated by the reference numeral 20a is the edge of the insulating film 20. When a photosensitive resin is used as the acrylic resin, the resin can be applied over the entire surface and then patterned using a well-known photolithography method, so that the insulating film 20 can be easily formed.

As shown in FIG. 4 and FIG.
A large number of scanning electrodes 6 are formed on the upper surface in a direction perpendicular to the scanning electrode routing wiring 16 below the insulating film 20 shown in FIG. On the insulating film 20, the same number of signal electrode lead wires 17 as the signal electrodes 7 on the upper substrate 2 are formed at positions isolated from the large number of scan electrodes 6. One end 17a of the signal electrode lead-out wiring 17 is located on the sealing material disposition area 15 on the side of the upper substrate 2 where the other end 7b of the signal electrode 7 extends.
And is formed so that the pitch between the wirings 17 matches the pitch between the signal electrodes 7. Then, as shown in FIG. 6, each signal electrode 7 of the upper substrate 2 and each signal electrode lead-out wiring 17 are electrically connected by conductive particles 21 (conductive material) mixed inside the sealing material 4. It is connected. On the other hand, as shown in FIG. 4, on the other end 17b side of the signal electrode routing wiring 17, the pitch between the wirings has a size corresponding to the pitch of the terminals of the signal electrode side driving IC 11, and the signal electrode routing is performed. The other end 17b of the wiring 17
Are electrically connected to the signal electrode side driving IC 11 as input terminals. The constituent material of the signal electrode lead-out wiring 17 may be any material as long as it is a conductive material similarly to the scan electrode side, but the scan electrode 6 formed on the same insulating film 20 is not required to complicate the manufacturing process. It is preferable to use the same material as the constituent material. Further, an input wiring 19 connected to the FPC 12 to input a driving signal to the signal electrode side driving IC 11 is formed.

FIG. 5 shows the combination of the structure under the insulating film 20 and the structure on the insulating film 20 described above. As shown in FIGS. 5 and 6, the scanning electrode lead-out wiring 16 is formed below the insulating film 20 and the scan electrode 6 is formed on the insulating film 20. Electrode 6

A contact hole 22 is always formed at the intersection with the scanning electrode lead-out wiring 1 at this intersection.
The electrical connection between the scanning electrode 6 and the scanning electrode 6
2 is realized.

Here, as an example of specific numerical values such as dimensions of the liquid crystal display device 1 having the above configuration, for example, the number of pixels is 200 × 200 dots, the width of each pixel is 140 μm, the pitch between pixels is 150 μm, Leading wiring 16 for scanning electrode
And the width of the wiring 17 for signal electrodes is 140 μm.
(The same width as the signal electrode 7, however, in FIG. 1 and FIGS. 3 to 5, the routing wiring is drawn much thinner than the signal electrode for easy distinction.) Specific resistance of 1.5 × 10 ^-4 Ω · cm and thickness of 70
nm, the specific resistance of the scanning wiring 16 and the signal wiring 17 is 1.5 × 10 ⁻⁴ Ω · cm, the thickness is 100 nm, the thickness of the insulating film 20 is 5 μm, and the insulating film 2

m.

In the liquid crystal display device 1 according to the present embodiment, both the scanning electrode wiring 16 for driving the scanning electrode 6 and the signal electrode wiring 17 for driving the signal electrode 7 are lower. Provided on the side substrate 3, and
The other ends 16a, 17a of the both wirings 16, 17 extend toward the same side of the lower substrate 3 as drive input terminals. With this configuration, the planar positional relationship between the upper substrate 2 and the lower substrate 3 is different from that in the related art in that the substrates are not arranged so as to protrude outside two adjacent sides of the display area, but are arranged in the conventional manner.
Only the lower substrate 3 is allowed to protrude outside one side of the display area 8, and this is used as the drive circuit section 9. Therefore, according to the liquid crystal display device 1 of the present embodiment, the area of the frame region outside the display region 8 can be reduced as compared with the related art, and the size can be reduced.

Further, the scanning wiring 16 is formed below the insulating film 20, and the signal wiring 17 is formed.
Are formed on the insulating film 20 so that the wirings 16 and 17 have a two-layer structure with the insulating film 20 interposed therebetween, and the wiring 16 for the scanning electrode and the wiring 17 for the signal electrode are formed. Since they can be arranged so as to overlap in a plane, the area occupied by the routing wiring formation portion can be further reduced.

Further, since the signal electrode side driving IC 11 and the scanning electrode side driving IC 10 are collectively mounted on one side of the lower substrate 3, the mounting operation of the driving element can be easily performed. The assembly work can be streamlined. Furthermore, since a common FPC 12 is connected instead of separately providing FPCs for supplying drive signals to the drive ICs 10 and 11, the liquid crystal display device 1 can be used in electronic devices and the like. When the FPC is incorporated, the handling of the FPC is facilitated, the space occupied by the FPC can be reduced, and the size of the electronic device can be reduced.

The signal electrode 7 on the upper substrate 2 and the signal electrode wiring 17 on the lower substrate 3 are electrically connected via conductive particles 21 mixed into the sealing material 4. Therefore, electrical connection between the signal electrode 7 and the signal electrode lead-out wiring 17 can be easily realized without using another connection member.

The positional relationship between the wiring for the signal electrode and the wiring for the scanning electrode and the wiring for the signal electrode may be reversed. Also,
Regarding the connection structure between the scanning electrode and the lead-out wiring for the scanning electrode in the above embodiment, for example, the design of the placement of the lead-out wiring for the scan electrode and the placement of the contact holes can be appropriately changed. In addition, it is needless to say that specific numerical values such as dimensions of each electrode and wiring illustrated in the above embodiment can be appropriately changed.

[0044]

As described above in detail, according to the present invention, each of the substrates constituting the liquid crystal display device is arranged in a display area as in the prior art as a planar positional relationship between the other substrate and the other substrate.
