In particular, the present invention relates to an electro-optical device including a pair of substrates that are arranged to face each other, and an electric device that includes the device.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, for example, a passive matrix type liquid crystal device (hereinafter simply referred to as “liquid crystal device”) that is used as an electro-optical device in many portable information devices, mobile phones, and the like is known.
[0003]
FIG. 6 shows a cross-sectional view of a conventional liquid crystal device 10. The liquid crystal device 10 includes two light transmissive substrates 12 and 14 facing each other. 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 transmissive substrate 14. The surface of the data line electrode 16 and the surface of the scanning line electrode 18 are covered with insulating films 20 and 22 and alignment films 24 and 26, respectively.
[0004]
The light transmissive 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 via a seal material 28. As a result, a space (cell gap) surrounded by the sealing material 30 is formed between the two substrates 12 and 14. A bead-shaped spacer (gap material) 30 is dispersed between the alignment films 24 and 26 in order to make the cell gap spacing uniform. Liquid crystal 32 is injected and sealed in the space surrounded by the sealing material 30.
[0005]
A connection terminal group 34 including a plurality of connection terminals is formed at the end of the light transmissive substrate 14. Each connection terminal included in the connection terminal group 34 is formed by wiring with a transparent conductive material such as ITO so as to be electrically connected to each of the plurality of scanning line electrodes 18.
[0006]
The light transmitting substrate 12 is formed with an overhanging portion that protrudes outward from the opposite light transmitting substrate 14, and an external terminal group 36 is formed on the surface of the overhanging portion. The external terminal group 36 includes a plurality of external terminals formed of a transparent conductive material such as ITO. In these external terminals, the data line electrode 16 extends and is conducted as it is, and a connection terminal group connected to the scanning line electrode 18 through an anisotropic conductive film (vertical conductive material) 38. 34 is included. All the external terminals included in the external terminal group 36 are connected to the conductive layer 44 of the external substrate 42 through the anisotropic conductive film 40 at the end of the overhanging portion. According to the above structure, appropriate signals can be supplied from the external substrate 42 to all the scanning line electrodes 18 and all the data line electrodes 18.
[0007]
In the conventional liquid crystal device 10, an anisotropic conductive film (vertical conductive material) 38 for conducting the connection terminal group 34 and the external terminal group 36, and a different for conducting the external terminal group 36 and the external substrate 42. The isotropic conductive film 40 is provided separately. Therefore, a certain amount of space (frame region that does not contribute to display) is formed between the two anisotropic conductive films 38 and 40. In the conventional liquid crystal device 10, a molding material 46 is embedded in the interval. For this reason, the external terminal group 36 and the connection terminal group 34 are not directly exposed to the atmosphere.
[0008]
[Problems to be solved by the invention]
However, the anisotropic conductive film (vertical conductive material) 38 that connects the connection terminal group 34 and the external terminal group 36 is formed at a position that enters the inside of the substrate 14 to some extent from the end of the light transmissive substrate 14. Sometimes. Therefore, 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 (vertical conductive material) 38.
[0009]
When the connection terminal group 34 made of a transparent conductive material such as ITO or the external terminal group 36 is exposed in such a space (gap) 48, corrosion (corrosion) due to electrolytic corrosion occurs in these terminals. A short circuit between the electrodes and a lighting failure due to this are likely to occur. In this regard, the structure of the conventional liquid crystal device 10 is not necessarily an ideal structure for ensuring the reliability of the connection terminal group 34 and the external terminal group 36.
[0010]
Further, in the conventional liquid crystal device 10, the interval (the frame region that does not contribute to display) secured between the two anisotropic conductive films 38 and 40 is not required for the function of the liquid crystal device, and the display Such an interval (frame region that does not contribute to display) exists even if the region to be displayed is the same, which hinders downsizing of the liquid crystal device. Furthermore, due to the recent market trend, the maximum display area is secured in the liquid crystal device, and the frame area that does not contribute to such display is minimized from the viewpoint of incorporation (installation) of the electronic equipment in the actual device. There is a strong demand to suppress it.
[0011]
The present invention has been made in view of the above problems, and provides an electro-optical device that can effectively prevent electrolytic corrosion of electrode terminals formed on a substrate and can promote downsizing of a liquid crystal device. Objective.
[0012]
[Means for Solving the Problems]

A connection terminal conductively connected to the electrode is formed on the opposing surface on one of the pair of substrates,
A first external terminal that is conductively connected to the electrode and a second external terminal that is electrically connected to the connection terminal through an anisotropic conductive member are formed on the opposite surface of the other substrate of the pair of substrates. And
The first and second external terminals and an external substrate conductively connected via an anisotropic conductive member,
An anisotropic conductive member interposed between the connection terminal and the second external terminal, and an anisotropic conductive member interposed between the first and second external terminals and the external substrate are: , Which are integrally formed.
[0013]
According to such a configuration of the present invention, the anisotropic conductive member is formed so as to protrude from the substrate including the connection terminal. 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. Furthermore, according to the above anisotropic conductive member, it is possible to completely cover the region for obtaining connection with the connection terminal and the region for obtaining connection with the external substrate among the external terminals. Therefore, according to the present invention, electrolytic corrosion of the connection terminal and the external terminal can be effectively prevented.
[0014]
In the present invention, since the anisotropic conductive member that conducts the external terminal to the connection terminal and the anisotropic conductive member that conducts the external terminal to the external substrate are integrated, to obtain these two conductions. It is possible to minimize the necessary space between the regions. For this reason, according to this invention, the space | interval of a board | substrate provided with a connection terminal and an external board | substrate can fully be narrowed, and size reduction of an apparatus can be accelerated | stimulated.
[0015]
(2) In the present invention, the one substrate and the other substrate are bonded together by a sealing material at a predetermined interval, and an area surrounding the electrode is formed by the sealing material, and the connection is made outside the area. Each of the 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.
[0016]
According to such a configuration, 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. Therefore, according to the present invention, the electrolytic corrosion of the terminal can be prevented even between the sealing material and the anisotropic conductive member.
[0017]
(3) In the present invention, the one substrate and the other substrate are bonded together with a sealing material at a predetermined interval, and a region surrounding the electrode is formed by the sealing material, and the anisotropic conductive member is It is desirable to constitute a part of the sealing material surrounding the region.
[0018]
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 structure, since a space cannot exist between the sealing material and the anisotropic conductive member, a good electrolytic corrosion preventing effect can be obtained.
[0019]
(4) In the present invention, it is desirable that the entire region of the sealing material is composed of an anisotropic conductive member.
[0020]
According to such a configuration, a sealing material for forming a sealed region and an anisotropic conductive member for obtaining necessary conduction can be integrally formed of the same material. Such a configuration can be easily realized as compared with the case where the sealing material is made of a material different from the anisotropic conductive member.
[0021]
(5) The electro-optical device according to the invention is desirably mounted on an electronic apparatus.
[0022]
By configuring the display unit of the electronic device with the electro-optical device according to the present invention, it is possible to impart excellent reliability to the display unit and to reduce the size of the electronic device.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0024]
[First Embodiment]
FIG. 1 is a plan view of two light transmissive substrates provided in the electro-optical device according to Embodiment 1 of the present invention. A light transmissive substrate 50 shown in FIG. 1A is one of the substrates constituting the electro-optical device, and is made of a light transmissive material such as glass. A plurality of data line electrodes 52 extending in parallel are formed on the light transmissive substrate 50. Each of the plurality of data line electrodes 52 extends and is connected to an external terminal 56 disposed at the end of the substrate via a wiring electrode 54. The data line electrode 52, the wiring electrode 54, and the external terminal 56 are made of a light transmissive conductive material such as ITO. Hereinafter, when the plurality of external terminals 56 electrically connected to the data line electrode 52 are collectively referred to as a “first external terminal group 58”.
[0025]
A plurality of external terminals 60 are further formed alongside the external terminals 56 at the end portion (projecting portion) of the light transmissive substrate 50. Similarly to the data line electrode 52 and the wiring electrode 54, the external terminal 60 is also made of a light transmissive conductive material such as ITO. Hereinafter, when the plurality of external terminals 60 are collectively referred to, they are referred to as a “second external terminal group 62”.
[0026]
Both the first external terminal group 58 and the second external terminal group 62 are arranged side by side along the same substrate side of the end portion (projecting portion) of the light transmissive substrate 50.
[0027]
A light-transmitting substrate 64 shown in FIG. 1B is the other substrate that is disposed to face the light-transmitting substrate 50 and is bonded via a sealing material 82. The light transmissive substrate 64 is also made of a light transmissive material such as glass, for example, like the light transmissive substrate 50 described above. A plurality of scanning line electrodes 66 extending in parallel are formed on the light transmissive substrate 64. Each of the plurality of scanning line electrodes 66 is connected to a connection terminal 70 disposed at the end of the substrate via a wiring electrode 68. The scanning line electrode 66, the wiring electrode 68, and the connection terminal 70 are made of a light transmissive conductive material such as ITO. Hereinafter, when a plurality of connection terminals 70 electrically connected to the scanning line electrode 66 are collectively referred to as a “connection terminal group 72”.
[0028]
Hereinafter, a case where the electro-optical device of the present embodiment is a passive matrix type liquid crystal device will be described as an example.
[0029]
FIG. 2 is a sectional view of a liquid crystal device according to an embodiment of the present invention. 2 shows a cross section obtained by cutting the light transmissive substrates 50 and 64 along the II-II linear electrodes shown in FIGS. 1A and 1B, respectively. .
[0030]
As shown in FIG. 2, the data line electrode 52 of the light transmissive substrate 50 is covered with an insulating film 74 and an alignment film 76. Similarly, the scanning line electrode 66 of the light transmissive substrate 64 is also covered with the insulating film 78 and the alignment film 80. The alignment films 76 and 80 are formed with alignment grooves in directions orthogonal to each other by rubbing.
[0031]
The light transmissive substrates 50 and 64 are arranged to face each other so that the data line electrode 52 and the scanning line electrode 66 covered by the alignment films 76 and 80 face each other in a state of being orthogonal to each other. The substrates 50 and 64 are bonded to each other through the sealing material 82 and the anisotropic conductive film 83 in the above state.
[0032]
As shown in FIG. 1, the sealing material 82 is formed in an annular shape on the periphery of the light-transmitting substrates 50 and 64, leaving an opening 84 for liquid crystal injection. The first external terminal group 58 described above has a predetermined length outside the region where the tip portion of each external terminal 56 is surrounded by the sealing material 82 (hereinafter, this region is referred to as “liquid crystal injection region 86” for convenience). Designed to extend. The second external terminal group 62 and the connection terminal group 72 described above are connected to the individual external terminals 60 outside the liquid crystal injection region 86 when the light-transmitting substrates 50 and 64 are bonded together. It is designed to face the terminal 70.
[0033]
As shown in FIG. 1, an anisotropic conductive film (ACF) 83, which is an anisotropic conductive member, is formed on the outside of the liquid crystal injection region 86, on the entire exposed portions of the external terminals 56 and 60, and on the connection terminals. 70 is formed in close contact with the sealing material 82 so as to cover the entire exposed portion of 70. In other words, the anisotropic conductive film 83 is sealed from the end surface of the overhanging portion of the light-transmitting substrate 50 because heat conduction is performed by a pressure tool (not shown) so that conduction at each portion is achieved and the resin melts and spreads. The region up to the material 82 is covered, and is formed so as to protrude from the end face of the projecting portion of the light transmissive substrate 64.
[0034]
Anisotropic Conductive Film (ACF) 83 is made by dispersing metal particles such as Ni and solder in a thermoplastic adhesive (resin), and applying metal plating to plastic to give particles with elasticity. 2 is a conductive film that is configured to have a dispersed structure and allows only conduction in a predetermined direction. In this embodiment, conduction in the vertical direction in FIG. 2, that is, the connection terminal group 72 and the second external terminal group. It is used so that conduction with 62 is allowed. Such an anisotropic conductive film 83 reliably prevents the first and second external terminal groups 58 and 62 and the connection terminal group 72 from being exposed to the atmosphere outside the liquid crystal injection region 86. At the same time, the external terminals 60 can be made conductive one by one, corresponding to each of the connection terminals 70 as appropriate.
[0035]
As shown in FIG. 2, spacers (gap materials) 88 such as beads or plastic balls are dispersed between the two light-transmitting substrates 50 and 64 in order to keep the distance between them constant. A liquid crystal injection region 86 surrounded by the sealing material 82 is filled with a twisted nematic liquid crystal (TN liquid crystal) 90 (hereinafter simply referred to as “liquid crystal 90”). The opening 84 (see FIG. 1) of the sealing material 82 is closed with the sealing material after the liquid crystal injection region 86 is filled with the liquid crystal 90.
[0036]
An external substrate 94 such as an FPC (Flexible Printed Circuit) substrate is electrically connected to the light transmissive substrate 50 through an anisotropic conductive film 83. A conductive layer 96 corresponding to the first and second external terminal groups 58 and 62 is formed on the external substrate 94. Necessary conduction is secured between the first and second external terminal groups 58 and 62 and the conductive layer 96 by the anisotropic conductive film 83.
[0037]
According to the above structure, all the data line electrodes 52 formed on the light transmissive substrate 50 and all the scanning line electrodes 66 formed on the light transmissive substrate 64 are desired from the external substrate 94. Can be supplied. 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 tip of the external substrate 94. Then, an appropriate drive signal is generated and output through the conductive layer 96, and is input to the external terminal groups 58 and 62 of the liquid crystal device, whereby the data signal and the data signal based on the display image are output for each row (line). Since the scanning signal to be selected is input at a predetermined timing, a desired electric field can be generated at the portion where the arbitrary data line electrode 52 and the arbitrary scanning line electrode 66 intersect (overlap) to display an image. Hereinafter, the intersecting portion is referred to as a “pixel”.
[0038]
Polarizing plates 98 and 100 having polarization characteristics orthogonal to each other are disposed on the surface of the light transmissive substrate 50 (lower surface in FIG. 2) and the surface of the light transmissive substrate 64 (upper surface in FIG. 2).
[0039]
In the liquid crystal device of this embodiment, in a pixel where no electric field is generated, the liquid crystal molecules maintain a state that allows light to travel straight (normally white). In this case, light transmission is blocked by the action of the two upper and lower polarizing plates 98 and 100 in the pixel region. On the other hand, in a pixel in which an electric field is generated, light transmission is allowed because liquid crystal molecules exhibit optical rotation. Therefore, according to the liquid crystal device of the present embodiment, by generating an appropriate drive signal on the external substrate 94, the state of each pixel can be controlled to display desired information.
[0040]
In order to allow the liquid crystal device to operate appropriately, as described above, necessary conduction is ensured between the connection terminal group 72 and the second external terminal group 62, and the first and second external terminal groups 62 are secured. It is necessary to ensure the necessary conduction between the conductive layer 96 and the conductive layer 96 of the external substrate 94. In the present embodiment, conduction at these two locations is ensured by the anisotropic conductive film 83.
[0041]
In the structure that secures the conduction at the two locations described above 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 external terminal group In terms of various variations and production techniques between the area necessary for ensuring conduction with 62 and the area necessary for obtaining conduction between the first and second external terminal groups 62 and the external substrate 94. A certain amount of interval is required in consideration of the above-mentioned restrictions. As a result, there is a problem that a part of the connection terminal 70 and the external terminals 56 and 60 are exposed to the atmosphere, or a large space is formed between the light transmissive substrate 64 and the external substrate 94.
[0042]
On the other hand, according to the structure of the present embodiment, all necessary conduction is ensured by the single anisotropic conductive film 83 that completely covers the exposed portions of the connection terminal 70 and the external terminals 56 and 60. The occurrence of such inconveniences can be avoided. That is, it extends over both the conductive portion between the electrodes formed on the upper and lower substrates (between the connection terminal 70 and the external terminal 70) and the conductive connection portion between the external terminals 56 and 60 and the conductive layer 96 of the external substrate 94. The same conductive material (anisotropic conductive film 83) is disposed and also used. For this reason, according to the structure of the present embodiment, the surface of the connection terminal 70 and the external terminals 56 and 60 is covered with the anisotropic conductive film 83 so that it is not exposed to the outside air and prevents electrolytic corrosion. While being able to give them excellent reliability, the space between the light transmissive 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 is reduced to the minimum necessary. The liquid crystal device can be reduced in size in a state where an equivalent display area is secured. Therefore, the electronic device can be easily incorporated into various electronic devices on which the liquid crystal device is mounted, and the electronic device itself can be reduced in weight and size.
[0043]
[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG.
[0044]
FIG. 3 is a plan view of two light transmissive substrates included in the electro-optical device according to the present embodiment. In FIG. 3, the same components as those shown in FIG.
[0045]
The electro-optical device according to the present embodiment has the same configuration as that of the device according to the first embodiment except that the seal member 102 is provided instead of the seal member 82 described above. That is, in the present embodiment, the two light transmissive substrates 50 and 64 are bonded to each other through the anisotropic conductive film 83 and the sealing material 102 which are anisotropic conductive members.
[0046]
As shown in FIG. 3, the sealing material 102 is formed in close contact with the side surface of the anisotropic conductive film 83 so as 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 transmissive substrates 50 and 64.
[0047]
According to the structure of this embodiment, a space for exposing the connection terminal 70 and the external terminals 56 and 60 to the atmosphere is not formed on the liquid crystal injection region 86 side of the anisotropic conductive film 83. More specifically, according to the structure of the present embodiment, each electrode around the sealing material 82 can be more reliably covered with the anisotropic conductive film 83 than the structure of the first embodiment. It can be surely prevented. Therefore, according to the electro-optical device of the present embodiment, further superior reliability can be obtained as compared with the device of the first embodiment.
[0048]
[Third Embodiment]
Next, Embodiment 3 of the present invention will be described with reference to FIG.
[0049]

[0050]
The electro-optical device according to the present embodiment has the same configuration as that of the device according to the first embodiment, except that the seal material 104 is provided instead of the seal material 82 and the anisotropic conductive film 83 described above. That is, in the present embodiment, the two light-transmitting substrates 50 and 64 are bonded to each other via the sealing material 104, the conduction between the connection terminal group 70 and the first external terminal group 62, and the first Further, the sealing material 104 ensures conduction between the second external terminal groups 58 and 62 and the external terminals 94 (see FIG. 2).
[0051]
As shown in FIG. 4, the sealing material 104 has substantially the same shape as the combination of the sealing material 102 and the anisotropic conductive film 83 shown in FIG. 3 by the anisotropic conductive member constituting the anisotropic conductive film 83. It is formed to become. 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, the sealing material and the anisotropic conductive film were separately provided in the above-described Example 1 and Example 2, but in this example, the substrate was further formed by forming the sealing material 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 unless the sealing material 104 is sandwiched between both electrodes formed on both substrates. It can be formed with a conductive film. Further, the sealing material 104 can be formed by a simple process as compared with the case where the sealing material 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.
