Abstract

An electro-optic device includes a first insulating substrate where a pixel electrode and a signal line are arranged on one surface side, a conductive layer formed on another surface of the first insulating substrate, and a conductive tape adhered to the conductive layer along at least one side of the first insulating substrate, where the conductive layer maintains a constant potential via the conductive tape.

Claims (29)

1. An electro-optic device comprising:

a first insulating substrate on a first surface of which a pixel electrode and a signal line are arranged;

a conductive layer formed on a second surface of the first insulating substrate;

a conductive tape adhered to the conductive layer along at least one side of the first insulating substrate;

a second insulating substrate which is arranged to face the first surface of the first insulating substrate;

a liquid crystal held between the first insulating substrate and the second insulating substrate;

an insulating member arranged to face the second surface of the first insulating substrate; and

a support body which supports the first insulating substrate,

wherein the insulating member includes a light guiding plate of a backlight device and an optical sheet arranged between the light guiding plate and the first insulating substrate,

the conductive tape is a double-sided tape on at least one surface of which a conductive adhesion layer is formed,

the first insulating substrate and the support body are fixed by the conductive tape, and

the conductive layer is in direct contact with the conductive tape and maintains a constant potential via the conductive tape.

2. The electro-optic device according to claim 1 ,

wherein the support body includes a metallic case, and

the conductive tape is adhered to the metallic case.

3. The electro-optic device according to claim 1 ,

wherein the conductive tape is adhered along at least the one side of the first insulating substrate and another side of the first insulating substrate.

4. The electro-optic device according to claim 3 ,

wherein the one side and the other side are adjacent, and the conductive tape along the one side and the conductive tape along the other side are separated.

5. The electro-optic device according to claim 1 , further comprising:

a wiring substrate connected to the first insulating substrate,

wherein a ground pattern is formed in the wiring substrate, and

the conductive tape is adhered to the ground pattern.

6. An electronic apparatus comprising

the electro-optic device according to claim 1 .

7. The electro-optic device according to claim 1 ,

wherein the conductive tape includes a metallic tape on at least one surface of which the conductive adhesion layer is formed.

8. The electro-optic device according to claim 7 ,

wherein the metallic film includes at least one of copper, nickel, stainless steel, aluminum, and an alloy thereof.
