In the liquid crystal device 1A of this embodiment, the first substrate 1
As 0, a substrate larger than the second substrate 20 is used, and when the first substrate 10 and the second substrate 20 are bonded together, the substrate side 201 of the second substrate 10 to the first substrate 1
The drive IC 7 is mounted and the flexible substrate 90 is connected using the portion 15 where 0 extends. In addition, the substrate side 201 of the second substrate and the first substrate
In the substrate 10 of the second substrate 20, inter-substrate conduction terminals 60 and 70 are formed in a portion overlapping the substrate side 201 of the second substrate 20, and the first substrate 10 and the second substrate 20 are bonded to each other. Then, the inter-substrate conduction terminals 60 and 70 are electrically connected to each other by a conductive material to be described later, and the inter-substrate conduction is performed.

Since the first sealing material 30A containing a conducting material is applied to the portion where the inter-substrate conduction is performed by the inter-conducting terminals 60 and 70, the type of the sealing material to be applied is selected even on the same side 303. It is necessary to switch, and the sealing material 30

[0012]

In order to solve the above problems, according to the present invention, a first substrate having a plurality of first driving electrodes and a plurality of first inter-substrate conduction terminals, and a second substrate A rectangular frame-shaped seal region that seals between a second substrate having a plurality of drive electrodes and a plurality of second inter-substrate conduction terminals formed thereon, and the first substrate and the second substrate that are arranged to face each other. And an electro-optical substance held in a region partitioned by the seal region, wherein the first inter-substrate conduction terminal and the second inter-substrate conduction terminal are provided in the seal region. In an electro-optical device coated with a first sealing material containing a conductive material for conduction and a second sealing material containing no conductive material, the first inter-substrate conductive layer among the four sides of the sealing region is applied. Between boards for carrying out board-to-board conduction by the common terminal and the second board-to-board conduction terminal On sides passing region is located, wherein said first sealing material is applied over the entire.

In the present invention, the first drive electrode and the first

After preparing a second substrate on which a plurality of second driving electrodes and second inter-substrate conduction terminals are formed, at least one of the first substrate and the second substrate is provided. In a method of manufacturing an electro-optical device in which a sealing material is applied in a rectangular frame shape, and then the first substrate and the second substrate are bonded to each other with the sealing material sandwiched therebetween, the sealing material is applied in a rectangular frame shape. When applying, apply the sealing material 4
A conductive material is contained on the entire side on which the inter-substrate conduction region for conducting inter-substrate conduction by the first inter-substrate conduction terminal and the second inter-substrate conduction terminal is located. The first sealing material is applied.

In the present invention, of the four sides of the rectangular frame-shaped seal area, the side where the inter-substrate conduction area is located is coated with the first seal material containing the conduction material. In the above, it is not necessary to properly use the first seal material containing the conductive material and the second seal material containing no conductive material. Therefore, the step of applying the sealing material can be efficiently performed. In addition, since the first seal material containing the conductive material is applied to the entire side where the inter-substrate conductive area is located, even if the application position of the first seal material is slightly deviated, the inter-substrate conductive area is formed. No troubles such as opening. Further, unless wiring with a narrow pitch is provided outside the side where the inter-substrate conduction region is located, even if the application position of the first sealing material is slightly shifted, there is no problem such as wiring short-circuiting. Therefore, since high accuracy is not required for the application position of the first sealing material, the application speed of the sealing material can be increased and the application step of the sealing material can be performed efficiently.

With this structure, in the electro-optical device of the present invention, for example, the wiring portions of the first electrode and the second electrode that are led out from the inside of the area defined by the seal area to the outside of the area. Of the four sides of the seal region, the narrow-pitch wiring portion formed at the pitch short-circuited by the conductive material passes through the side where the inter-substrate conduction region is not formed, and on the side. The second sealing material is applied over the entire surface.

According to the method of manufacturing an electro-optical device of the present invention having such a structure, for example, in the first substrate and the second substrate, it is led out from inside the area defined by the seal area to outside the area. Among the wiring portions of the first electrode and the second electrode, the narrow pitch wiring portion formed at the pitch short-circuited by the conductive material is the inter-substrate portion among the four sides to which the sealing material is applied. A second sealing material containing no conductive material is applied over the entire side where the conductive region is not formed and over the side.

According to this structure, in the narrow pitch wiring portion, of the four sides to which the sealing material is applied, the side where the inter-substrate conduction region is not formed is passed through and the conduction is performed over the entire side. Since the second sealing material containing no material is applied, it is possible to avoid the problem that the narrow pitch wiring portions are short-circuited by the conductive material. Also, around here,
Since the board-to-board conductive area is not formed, even if the application position of the second sealing material is slightly deviated, a problem such as opening of the board-to-board conductive portion does not occur. Therefore, since high accuracy is not required for the application position of the second sealing material, the application speed of the sealing material can be increased and the application process of the sealing material can be efficiently performed.

In the present invention, the electro-optical material is liquid crystal.

The electro-optical device to which the present invention is applied is used as a display section of various electronic devices such as a mobile phone and a mobile computer.

The inter-substrate conduction terminals 60 and 70 are electrically connected to each other by an inter-substrate conductive material, which will be described later, to establish conduction between the substrates.

Here, the inter-board conduction terminals 60 and 70 are
Unlike the conventional liquid crystal device described with reference to FIGS. 9 to 14, four sides 301, 302, 303, 30 of the side of the image display area 2, that is, the rectangular frame-shaped seal area 30.

(Structure of Sealing Material and Method of Manufacturing Liquid Crystal Device 1) In constructing such a liquid crystal device 1,
In the present embodiment, a first sealing material containing a conducting material and a second sealing material not containing a conducting material are applied to predetermined regions in the sealing region 30, respectively, and the first substrate 10 and the first substrate 10 Two
The substrate 20 is bonded to the substrate 20, and the inter-substrate conduction is performed. Such a configuration will be described while explaining the method of manufacturing the liquid crystal device 1. When manufacturing the liquid crystal device 1, generally, both the first substrate 10 and the second substrate 20 are large substrates capable of taking a large number of these substrates 10 and 20, respectively, and the light-shielding film 23 and the collar. Filter 7R, 7
The steps of forming G, 7B, the planarizing film 21, the electrode patterns 40, 50, etc. are performed, and after bonding such a large substrate with a sealing material, it is cut into a size corresponding to a single liquid crystal device 1. In the following description, in order to facilitate understanding of the features of the present invention, it is assumed that each process is performed in the state of the single-sized first substrate 10 and the second substrate 20.

In manufacturing the liquid crystal device 1 of the present embodiment, as shown in FIG. 2, the first substrate 10 and the second substrate 20 are manufactured. Here, as shown in FIG.
5, the first electrode pattern 40 and the inter-substrate conduction terminal 60 are formed, and the second electrode pattern 50 and the inter-substrate conduction terminal 70 are formed on the second substrate 20, as shown in FIG. Is formed. In addition, in FIG. 4 and FIG.
The outer peripheral edge of the image display area 2 is shown by a one-dot chain line L1, and the seal area 30 is shown by a two-dot chain line L2.

Next, the first substrate 10 and the second substrate 2
Of 0, for example, the sealing material is applied to the first substrate 10 as described below.

First, as shown in FIG. 4, the four sides 301, 302, 303, 304 of the rectangular frame-shaped seal area 30.
Of these, the first sealing material 30A containing a conductive material is applied over the entire sides 301 and 302 where the inter-substrate conductive areas where the inter-substrate conductive terminals 60 and 70 conduct the inter-substrate are located.

Further, among the four sides 301, 302, 303, 304 of the rectangular frame-shaped seal area 30, in the first electrode pattern 40, the wiring having a narrow pitch from the area defined by the seal area 30 to the outside of the area. On the side 303 from which the portion 41 is led out, since the inter-substrate conduction region for conducting the inter-substrate conduction by the inter-substrate conduction terminals 60 and 70 is not formed,
A second sealing material 30B containing no conductive material is applied over the entire surface.

On the other side 304, the first sealing material 3
Either 0A or the second sealing material 30B may be applied, but in the present embodiment, the second sealing material 30B containing no conductive material is applied.

Thereafter, the first substrate 10 and the second substrate 20 are bonded to each other so as to sandwich the sealing materials 30A and 30B, and then liquid crystal is injected from the injection port 32 between the substrates, and then the injection port is filled. 32 is sealed with the sealing material 31.

(Main Effect of this Embodiment) As described above, in the liquid crystal device 1 of this embodiment, as shown in FIGS. 3A and 4, inter-substrate conduction terminals 60 and 70 perform inter-substrate conduction. The wiring portion 41 having a narrow pitch is passed through the side 303 side where the inter-substrate conduction region is not formed, and the side 303 is entirely coated with the second sealing material 30B containing no conduction material. Therefore, even if the pitch of the wiring portions 41 is narrow, it is possible to avoid the problem that the wiring portions 41 are short-circuited due to the conductive material. Further, since it is not necessary to apply the second sealing material 30B over the entire side 303 and apply the first sealing material 30A to a part thereof,
The application process of the sealing material can be performed efficiently.

Further, as shown in FIG. 3B, four sides 301, 302, 303 of the rectangular frame-shaped seal area 30 are formed.
Of the 304, sides 301, 3 where the inter-substrate conduction region for conducting the inter-substrate conduction by the inter-substrate conduction terminals 60, 70 is located.
Since 02 is coated with the first sealing material 30A containing a conductive material, the inter-substrate conduction can be performed by the inter-substrate conduction terminals 60 and 70. Here, on the sides 301 and 302, the first sealing material 30A containing a conductive material is applied over the entire area regardless of whether or not the terminals 60 and 70 for inter-substrate conduction are formed. That is, on the sides 301 and 302, the inter-substrate conduction terminals 60 and 70 are provided.
Although the inter-substrate conduction is not performed in the region adjacent to the region in which the inter-substrate conduction is performed by (1), the first sealing material 30A containing the conduction material is applied. However, the wiring does not pass through here, and even if the wiring is passed through here, only the wiring with a wide pitch is passed through, so even if the first sealing material 30A containing the conductive material is applied, the wiring is No short circuit occurs. Therefore, the side 301 of the seal area 30,
Sealing material 30A, 30B to be applied at an intermediate position of 302
There is no need to switch the type. Therefore, the sealing material applying step can be efficiently performed.

Further, even if the coating positions of the sealing materials 30A and 30B are slightly displaced, no problem occurs. For example, side 30
Even if the application position of the first sealing material 30A is deviated in the vertical direction in Nos. 1 and 302, a short-circuit does not occur because the wiring having a narrow pitch does not pass there. Further, even if the application position of the second sealing material 30B on the side 303 shifts in the lateral direction, since the inter-substrate conduction is not performed there, no trouble such as opening of the inter-substrate conduction portion occurs. Therefore, the reliability of the liquid crystal device 1 is improved. In addition, the sealing material 30A,
Since high accuracy is not required for the coating position of 30B, the sealing material coating step can be efficiently performed in that the coating speed of the sealing materials 30A and 30B can be increased.
