Description

The present invention relates to an electro-optical device in which inspection terminals are arranged in a non-display area of a first substrate, and an electronic apparatus including the electro-optical device.

In an electro-optical device such as a liquid crystal device, the non-display area outside the display area of the substrate is
A drive circuit is disposed, and a connection terminal to which a flexible wiring board or the like is connected is disposed in the non-display area. In the manufacturing process of the electro-optical device, an electrical signal or the like is output from the input inspection terminal to the drive circuit, while the drive circuit is inspected based on the signal output from the drive circuit to the output inspection terminal. . Here, the inspection terminal becomes unnecessary after performing the inspection process. Therefore, when various methods for the substrate are performed in the state of a large substrate and the method for cutting the large substrate is used after the substrate manufacturing process is completed, inspection terminals are provided in regions other than the region from which the substrate is cut out. Has been proposed (see Patent Document 1).
.

JP 2003-271067 A

In the method described in Patent Document 1, there is a problem that the number of substrates that can be cut out from the large substrate is reduced because a large portion of the large substrate is wasted.

Therefore, as shown in FIG. 8, it is preferable to provide inspection terminals (first inspection terminal 11 and second inspection terminal 12) on the substrate 10x. For example, in the configuration example shown in FIG. 8, in the non-display area 10c outside the display area 10a of the substrate 10x, a plurality of connection terminals 1 along the first side 10e.
02, and the central portion of the second side 10h adjacent to the first side 10e or the second side 10e.
A first inspection terminal 11 and a second inspection terminal 12 are provided at the central portion of the third side 10g facing h.

However, in the case of the configuration shown in FIG. 8, the following problem occurs in the manufacturing process of the substrate 10x. For example, when the rubbing process is performed on the alignment film formed on the substrate 10x along a direction parallel or substantially parallel to the first side, the alignment film is generated due to the unevenness of the first inspection terminal 11 and the second inspection terminal 12. A streak or the like reaches the display area 10a to cause an alignment failure, resulting in a problem that display quality is deteriorated. Further, even in a process other than the rubbing process, when water washing or wet processing is performed on the large substrate 10w from which a large number of substrates 10x can be obtained, the first inspection terminal 11 and the second inspection terminal 12 are caused by the unevenness of the first inspection terminal 11 and the second inspection terminal 12. As a result of the cleaning water or the processing liquid drooping from the inspection terminal 11 and the second inspection terminal 12 to the display area 10a, impurities are attached to the display area 10a. For example, the surface properties of the display area 10a vary and display quality is deteriorated. Problems occur.

In view of the above problems, an object of the present invention is to provide an electro-optical device and an electronic apparatus that can suppress deterioration in display quality caused by an inspection terminal even when the inspection terminal is provided along the side of the substrate. Is to provide.

In order to solve the above problem, an electro-optical device according to the present invention includes a plurality of connection terminals arranged along the first side of the first substrate in a non-display region outside the display region of the first substrate. A first drive circuit disposed along a second side adjacent to the first side of the first substrate in the non-display region, and a plurality of circuits disposed along the second side in the non-display region. And the plurality of first inspection terminals are displaced in the extending direction of the second side with respect to a projection range in which the display area is projected in the extending direction of the first side. It is provided in a different position.

In the present invention, the first inspection terminal is formed along the second side in the non-display area of the first substrate. The plurality of first inspection terminals extend the display area in the extending direction of the first side. Is shifted in the extending direction of the second side with respect to the projection range projected onto. For this reason, when water washing or wet processing is performed on the first substrate, even if the first side is directed in the vertical direction while avoiding the influence of the connection terminal, the cleaning water or the processing liquid is applied from the first inspection terminal to the display area. It is difficult for the situation of drooping to occur. Therefore, variations in the surface properties of the display area can be suppressed. Further, even if the rubbing process is performed in a direction parallel to or substantially parallel to the first side while avoiding the influence of the connection terminal, streaks or the like due to the first inspection terminal are unlikely to occur. Therefore, even when the inspection terminals are provided along the sides of the substrate, it is possible to suppress the deterioration in display quality caused by the inspection terminals.

In the present invention, it is preferable that the plurality of first inspection terminals are arranged in a line along the second side. According to this configuration, the width of the space occupied by the first inspection terminal can be reduced in the direction in which the first side extends.

In the present invention, some terminals of the plurality of first inspection terminals are provided at positions shifted to one side in the extending direction of the second side with respect to the projection range, and the other some terminals are Further, it is possible to adopt a configuration provided at a position shifted to the other side in the extending direction of the second side with respect to the projection range.

In the present invention, the plurality of first inspection terminals may be provided at positions shifted to one side in the extending direction of the second side with respect to the projection range.

A plurality of second inspection terminals, and the plurality of second inspection terminals are shifted in the extending direction of the third side with respect to a range in which the display area is projected in the extending direction of the first side. The structure provided at the position can be employed.

In the present invention, a configuration in which the plurality of first terminals and the plurality of second inspection terminals are arranged symmetrically with respect to the display area may be employed.

Furthermore, the second polarizing plate 115d is a polarizing plate that blocks p-polarized light and transmits s-polarized light. Therefore, the liquid crystal light valve 115 is configured to emit red light R in accordance with the image signal.

Since it is reflected by 5a and 125b, it is s-polarized light.

The λ / 2 phase difference plate 117a is an optical element that converts s-polarized light incident on the liquid crystal light valve 117 into p-polarized light. The first polarizing plate 117b is a polarizing plate that blocks s-polarized light and transmits p-polarized light. The electro-optical device 100 (blue liquid crystal panel 100B) is configured to convert p-polarized light to s-polarized light (circularly polarized light or elliptically polarized light if it is a halftone) by modulation according to an image signal. Furthermore, the second polarizing plate 117d is a polarizing plate that blocks p-polarized light and transmits s-polarized light. Therefore, the liquid crystal light valve 117 is controlled by the blue light B according to the image signal.
The modulated blue light B is emitted toward the cross dichroic prism 119. The λ / 2 phase difference plate 117a and the first polarizing plate 117b are arranged in contact with the glass plate 117e.

The relay system 120 includes relay lenses 124a and 124b and reflection mirrors 125a and 125b.

The dichroic film 119a is a film that reflects blue light B and transmits green light G, and the dichroic film 119b is a film that reflects red light R and transmits green light G. Therefore, the cross dichroic prism 119 combines the red light R, the green light G, and the blue light B modulated by each of the liquid crystal light valves 115 to 117,
The light is emitted toward the projection optical system 118.

The light that enters the cross dichroic prism 119 from the liquid crystal light valves 115 and 117 is s-polarized light, and the cross dichroic prism 1 from the liquid crystal light valve 116.
The light incident on 19 is p-polarized light. Thus, by making the light incident on the cross dichroic prism 119 into different types of polarized light, the light incident from the liquid crystal light valves 115 to 117 in the cross dichroic prism 119 can be synthesized. Here, in general, the dichroic films 119a and 119b are excellent in s-polarized reflection transistor characteristics. For this reason, red light R and blue light B reflected by the dichroic films 119a and 119b are s-polarized light, and green light G transmitted through the dichroic films 119a and 119b is p-polarized light. The projection optical system 118 has a projection lens (not shown) and is configured to project the light combined by the cross dichroic prism 119 onto the screen 111.
