[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an electro-optical device and an electronic apparatus equipped with the device. In particular, the present invention relates to an electro-optical device including a pair of substrates arranged to face each other, and an electric apparatus on which the device is mounted.

[0002]

2. Description of the Related Art Conventionally, for example, a passive matrix type liquid crystal device (hereinafter, simply referred to as a "liquid crystal device"), which is used in many portable information devices and cellular phones, etc., is known as an electro-optical device. .

FIG. 6 is a sectional view of a conventional liquid crystal device 10. The liquid crystal device 10 includes two opposing light-transmitting substrates 12
And 14. A plurality of data line electrodes 16 extending in parallel with each other are formed of a transparent conductive material such as ITO on the opposing surface of one light transmissive substrate 12.
A plurality of scanning line electrodes 18 extending in parallel with each other are formed of a transparent conductive material on the opposite surface of the other light transmitting substrate 14. The surfaces of the data line electrode 16 and the scanning line electrode 18 are covered with insulating films 20 and 22 and alignment films 24 and 26, respectively.

The light-transmitting substrates 12 and 14 are arranged so that the data line electrodes 16 and the scanning line electrodes 18 face each other so as to be orthogonal to each other, and are bonded together with a seal material 28 interposed therebetween. As a result, a space (cell gap) surrounded by the sealing material 30 is formed between the two substrates 12 and 14. A bead-like spacer (gap material) 3 is provided between the alignment films 24 and 26 in order to make the cell gap interval uniform.
0 is sprayed. A liquid crystal 32 is injected and sealed in a space surrounded by the sealant 30.

A connection terminal group 34 including a plurality of connection terminals is formed at an end of the light transmitting substrate 14. Each connection terminal included in the connection terminal group 34 is formed of a transparent conductive material such as ITO so as to be electrically connected to each of the plurality of scanning line electrodes 18.

The light transmissive substrate 12 has an overhang formed on the outer side of the other opposing light transmissive substrate 14, and an external terminal group 36 is formed on the surface of the overhang. The external terminal group 36 includes a plurality of external terminals formed of a transparent conductive material such as ITO. The data line electrode 16 is formed to extend as it is to be electrically connected to those external terminals, and the anisotropic conductive film (upper / lower conductive material) 38
And those electrically connected to the connection terminal group 34 connected to the scanning line electrode 18 through the line. All the external terminals included in the external terminal group 36 are connected to the conductive layer 44 of the external substrate 42 via the anisotropic conductive film 40 at the end of the overhang. According to the above structure, all the scanning line electrodes 1
8 and all data line electrodes 18 can be supplied with appropriate signals from the external substrate 42.

In the conventional liquid crystal device 10, an anisotropic conductive film (upper / lower conductive material) 38 for conducting the connection terminal group 34 and the external terminal group 36, the external terminal group 36 and the external substrate 4
2 is provided separately from the anisotropic conductive film 40 for conducting the conductive film 2. Therefore, the two anisotropic conductive films 3
A certain interval (frame area not contributing to display) is formed between 8 and 40. In the conventional liquid crystal device 10, a molding material 46 is embedded in the space. Therefore, the external terminal group 36 and the connection terminal group 34 are not directly exposed to the atmosphere.

[0008]

However, the anisotropic conductive film (upper / lower conductive material) 38 for connecting the connection terminal group 34 and the external terminal group 36 has a certain distance from the end of the light transmissive substrate 14. It may be formed at the position where it enters inside. For this reason, in the conventional liquid crystal device 10,
As shown in FIG. 6, a space (gap) 48 may remain between the molding material 46 and the anisotropic conductive film (upper / lower conductive material) 38.

When the connection terminal group 34 or the external terminal group 36 made of a transparent conductive material such as ITO is exposed in such a space (gap) 48, the terminals are corroded by corrosion (corrosion). ) Occurs, and short-circuiting between the electrodes and lighting failure due to the short-circuit easily occur. In this regard, the structure of the conventional liquid crystal device 10 is not always an ideal structure for ensuring the reliability of the connection terminal group 34 and the external terminal group 36.

Furthermore, in the conventional liquid crystal device 10, the space (frame region not contributing to display) secured between the two anisotropic conductive films 38 and 40 is not required for the function of the liquid crystal device. In addition, even if the displayed area is the same, such an interval (a frame area that does not contribute to display) exists, which hinders downsizing of the liquid crystal device.
Furthermore, in view of recent market trends, a maximum display area is secured in a liquid crystal device, and a frame area that does not contribute to such display is minimized from the viewpoint of incorporation (mounting) of an electronic device into an actual device. There is a strong demand for suppression.

The present invention has been made in view of the above problems, and provides an electro-optical device capable of effectively preventing electrolytic corrosion of an electrode terminal formed on a substrate and promoting downsizing of a liquid crystal device. The purpose is to do.

According to such a configuration of the present invention, the anisotropic conductive member is formed so as to protrude from the substrate having the connection terminals. In this case, no space remains inside the end face of the substrate, and the tip of the connection terminal formed near the end face of the substrate can be completely covered with the anisotropic conductive member. Further, according to the anisotropic conductive member described above, of the external terminals, a region for obtaining connection with the connection terminal and a region for obtaining connection with the external substrate can be completely covered. Therefore, according to the present invention, electrolytic corrosion of the connection terminal and the external terminal can be effectively prevented.

In the present invention, the anisotropic conductive member for conducting the external terminal to the connection terminal and the anisotropic conductive member for conducting the external terminal to the external substrate are integrated.
The interval between the regions required to obtain these two conductions can be minimized. For this reason, according to the present invention, the space between the substrate having the connection terminals and the external substrate can be sufficiently reduced, and the miniaturization of the device can be promoted.

(2) According to the present invention, the one substrate and the other substrate are bonded to each other with a predetermined distance from each other by a sealing material, and a region surrounding the electrode is formed by the sealing material, and the outside of the region is formed. Each of the connection terminal, the first external terminal, and the second external terminal is disposed, and the anisotropic conductive member covers the connection terminal, the first external terminal, and the second external terminal. It is desirable to have.

According to this structure, a sealed region can be formed between the pair of substrates, and a space can be prevented from remaining between the sealing material and the anisotropic conductive member. Can be. Therefore, according to the present invention, electrolytic corrosion of the terminal can be prevented even between the sealing material and the anisotropic conductive member.

(3) In the present invention, the one substrate and the other substrate are bonded to each other with a predetermined distance from each other by a sealing material, and a region surrounding the electrode is formed by the sealing material, and Preferably, the conductive member forms a part of the sealing material surrounding the region.

According to such a configuration, a sealed region can be formed between the pair of substrates using the anisotropic conductive member. According to such a configuration, since no space can exist between the sealing material and the anisotropic conductive member, a good electrolytic corrosion preventing effect can be obtained.

(4) In the present invention, it is preferable that the entire region of the sealing material is formed of an anisotropic conductive member.

According to such a configuration, the sealing material for forming the sealed area and the anisotropic conductive member for obtaining the necessary conduction can be integrally formed of the same material. Such a configuration can be easily realized as compared with the case where the sealant is made of a material different from the material of the anisotropic conductive member.

(5) The electro-optical device according to the present invention is desirably mounted on electronic equipment.

According to the electro-optical device according to the present invention, the display section of the electronic device can be provided with excellent reliability and the size of the electronic device can be reduced.

Hereinafter, the case where the electro-optical device of the present embodiment is a passive matrix type liquid crystal device will be described as an example.

FIG. 2 is a sectional view of a liquid crystal device according to an embodiment of the present invention. In FIG. 2, the light-transmitting substrates 50 and 64 are shown in FIGS. 1A and 1B, respectively.
The cross section obtained by cutting along the II-II linear electrode is shown.

As shown in FIG. 2, the data line electrode 52 of the light transmitting substrate 50 is covered with an insulating film 74 and an alignment film 76. Similarly, the scanning line electrodes 6 on the light transmitting substrate 64

The light transmitting substrates 50 and 64 are
Data line electrode 52 and scanning line electrode 6 covered with 6, 80
6 are arranged so as to face each other in a state of being orthogonal to each other. The substrates 50 and 64 are bonded to each other via the sealing member 82 and the anisotropic conductive film 83 in the above-described state.

As shown in FIG. 1, the sealing material 82 is provided with the light transmitting substrates 50 and 6 except for an opening 84 for injecting liquid crystal.
4 is formed in an annular shape at the peripheral portion. The above-described first external terminal group 58 is arranged such that the tip of each external terminal 56 has a predetermined length outside a region surrounded by the sealing material 82 (hereinafter, this region is referred to as a “liquid crystal injection region 86” for convenience). It is designed to extend. The second external terminal group 6 described above

An anisotropic conductive film (Anis)
As shown in FIG. 1, the sealing material covers the entire exposed portion of the external terminals 56 and 60 and the entire exposed portion of the connection terminal 70 outside the liquid crystal injection region 86 as shown in FIG. It is formed in a state of being in close contact with 82. In other words, the anisotropic conductive film 83 is heated and pressed by a pressing tool (not shown), so that conduction is achieved in each part and the resin is melted and spread, so that the end face of the protruding part of the light transmitting substrate 50 is sealed. The light transmissive substrate 64 is formed so as to cover the region up to the material 82 and protrude from the end face of the protruding portion of the light transmissive substrate 64.

Anisotropic Conductive F
ilm / ACF) 83 has a material in which metal particles such as Ni and solder are dispersed in a thermoplastic adhesive (resin), a material in which plastic is plated with metal, and particles having elasticity are dispersed. In the present embodiment, the conductive terminals are vertically conductive in FIG. 2, that is, the connection terminal group 72 and the second external terminal group 62.
Is used so that conduction with the terminal is permitted. According to such an anisotropic conductive film 83, the first and second external terminal groups 58 and 62 and the connection terminal group 72 are reliably prevented from being exposed to the atmosphere outside the liquid crystal injection region 86. At the same time, corresponding to each of the connection terminals 70 as appropriate,
The external terminals 60 can be conducted one by one.

As shown in FIG. 2, two light transmitting substrates 50 are provided.
A spacer (gap material) 88 such as a bead or a plastic ball is scattered between and 64 so as to keep the distance therebetween. The liquid crystal injection region 86 surrounded by the sealing material 82 has a twisted nematic liquid crystal (T
N liquid crystal) 90 (hereinafter simply referred to as “liquid crystal 90”). After the liquid crystal 90 is filled in the liquid crystal injection region 86, the opening 84 (see FIG. 1) of the sealing material 82
It is closed with a sealing material.

The light-transmitting substrate 50 has an anisotropic conductive film 83
, An external board 94 such as an FPC (Flexible Printed Circuit) board is electrically connected. Conductive layers 96 corresponding to the first and second external terminal groups 58 and 62 are formed on the external substrate 94. First and second
The necessary conduction is secured by the anisotropic conductive film 83 between the external terminal groups 58 and 62 and the conductive layer 96.

According to the above-described structure, the external substrate is connected to all the data line electrodes 52 formed on the light transmitting substrate 50 and all the scanning line electrodes 66 formed on the light transmitting substrate 64. A desired signal can be supplied from 94. Therefore, according to the liquid crystal device of the present embodiment, a liquid crystal driving (driver) IC or an electronic component is mounted on the external substrate 94, or the liquid crystal driving (driver) IC is electrically connected to the end of the external substrate 94. Then, an appropriate drive signal is generated and output through the conductive layer 96, and the external terminal group 5 of the liquid crystal device is output.
8, 62, a data signal based on a display image and a scanning signal for selecting a data signal for each row (line) are input at a predetermined timing, so that an arbitrary data line electrode 52 and an arbitrary scanning line are input. Intersect (overlap) with the electrode 66
An image can be displayed by generating a desired electric field in the portion. Hereinafter, the above intersection is referred to as a “pixel”.

On the surface of the light-transmitting substrate 50 (the lower surface in FIG. 2) and the surface of the light-transmitting substrate 64 (the upper surface in FIG. 2), polarizing plates 98 and 100 having polarization characteristics orthogonal to each other are arranged. ing.

In the liquid crystal device of this embodiment, in the pixel where no electric field is generated, the liquid crystal molecules maintain a state in which the light is allowed to go straight (normally white). In this case, in the pixel area, light transmission is blocked by the action of the two upper and lower polarizing plates 98 and 100. On the other hand, in a pixel in which an electric field is generated, liquid crystal molecules exhibit optical rotation, so that light transmission is allowed. Therefore, according to the liquid crystal device of the present embodiment, by generating an appropriate drive signal on the external substrate 94,
Desired information can be displayed by controlling the state of each pixel.

In order to properly operate the liquid crystal device, necessary conduction between the connection terminal group 72 and the second external terminal group 62 is ensured as described above, and the first and second external terminals are required. It is necessary to ensure necessary conduction between the terminal group 62 and the conductive layer 96 of the external substrate 94. In the present embodiment, conduction at these two locations is both ensured by the anisotropic conductive film 83.

In the above-described structure in which conduction at two locations is secured by using two anisotropic conductive films formed separately, that is, in the conventional structure shown in FIG. 6, the connection terminal group 72 and the second A region necessary for securing conduction with the external terminal group 62, the first and second external terminal groups 62 and the external substrate 94
Considering various variations and restrictions on production technology, a certain amount of space is required between a region necessary for obtaining conduction with the device. As a result, the connection terminal 70 and the external terminal 5
A disadvantage arises in that a part of 6, 60 is exposed to the atmosphere, or a large space is formed between the light transmitting substrate 64 and the external substrate 94.

On the other hand, according to the structure of the present embodiment, all necessary conduction is secured by the single anisotropic conductive film 83 that completely covers the exposed portions of the connection terminals 70 and the external terminals 56 and 60. Therefore, occurrence of those inconveniences can be avoided. That is, the conductive portion between the electrodes formed between the upper and lower substrates (between the connection terminal 70 and the external terminal 70) and the external terminal 5
The same conductive material (anisotropic conductive film 83) is arranged and shared over both conductive connection portions between the conductive layers 6 and 60 and the conductive layer 96 of the external substrate 94. For this reason, according to the structure of this embodiment, since the surfaces of the connection terminals 70 and the external terminals 56 and 60 are covered with the anisotropic conductive film 83, they are not exposed to the outside air, thereby preventing electrolytic corrosion. It is possible to provide them with excellent reliability, and reduce the distance between the light-transmitting substrate 64 and the external substrate 94, that is, the frame region, which is a region that does not contribute to the display of the liquid crystal device, to a minimum. In addition, the size of the liquid crystal device can be reduced while maintaining the same display area. Accordingly, it is easy to incorporate the liquid crystal device into various electronic devices, and the electronic device itself can be reduced in weight and size at the same time.

[Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIG.

FIG. 3 is a plan view of two light-transmitting substrates provided in the electro-optical device according to the present embodiment. In FIG. 3, the same components as those shown in FIG. 1 are denoted by the same reference numerals, and redundant description will be omitted.

The electro-optical device according to the present embodiment is different from the electro-optical device according to the first embodiment in that a seal member 102 is provided in place of the seal member 82 described above.
It has a configuration similar to that of the device of the first embodiment. That is, in the present embodiment, the two light-transmitting substrates 50 and 64 are bonded to each other via the anisotropic conductive film 83 which is an anisotropic conductive member and the sealing material 102.

As shown in FIG. 3, the sealing material 102 is formed in close contact with the side surface of the anisotropic conductive film 83 to realize an annular shape together with the anisotropic conductive film 83. In other words, in the present embodiment, the anisotropic conductive film 83 is used as a part for forming the liquid crystal injection region 86 between the two light transmitting substrates 50 and 64.

According to the structure of this embodiment, no space is formed on the liquid crystal injection region 86 side of the anisotropic conductive film 83 to expose the connection terminals 70 and the external terminals 56 and 60 to the atmosphere. More specifically, according to the structure of the present embodiment, each electrode around the seal member 82 can be covered with the anisotropic conductive film 83 more reliably than the structure of the first embodiment, It can be reliably prevented. Therefore, according to the electro-optical device of the present embodiment, it is possible to obtain higher reliability than the device of the first embodiment.

[Third Embodiment] Next, a third embodiment of the present invention will be described with reference to FIG.

FIG. 4 is a plan view of two light-transmitting substrates provided in the electro-optical device according to the present embodiment. In FIG. 4, the same parts as those shown in FIG. 1 or FIG.
The same reference numerals are given and duplicate descriptions are omitted.

The electro-optical device according to the present embodiment is different from the above-described sealing material 82 and anisotropic conductive film 83 in that the sealing material 1
It has the same configuration as that of the device of the first embodiment except that the device of the first embodiment is provided. That is, in the present embodiment, 2
The two light-transmitting substrates 50 and 64 are bonded to each other via a sealing material 104, conduction between the connection terminal group 70 and the first external terminal group 62, and the first and second external terminal groups 58, Conduction between the external terminal 62 and the external terminal 94 (see FIG. 2) is ensured by the sealant 104.

As shown in FIG. 4, the sealing material 104 is made of an anisotropic conductive member constituting the anisotropic conductive film 83 as shown in FIG.
Are formed so as to have substantially the same shape as the combination of the sealing material 102 and the anisotropic conductive film 83 shown in FIG. According to such a sealing material 104, both the function of the sealing material 102 and the function of the anisotropic conductive film 83 can be realized. That is, although the sealant and the anisotropic conductive film are separately provided in the above-described Embodiments 1 and 2, in this embodiment, the substrate is further formed by forming the sealant with the anisotropic conductive film. In the above, integral formation is performed in the same process. Further, even if the sealing material 104 surrounding the periphery of the substrate is formed of an anisotropic conductive film, there is no problem as long as the sealing material 104 is not sandwiched between both electrodes formed on both substrates. A conductive film can be formed. Further, the sealant 104 can be formed by a simpler process than when the sealant 102 and the anisotropic conductive film 83 are separately formed. Therefore, according to the structure of the present embodiment, a device having the same function as the device of the first or second embodiment can be realized more easily.
