Abstract

An electro-optic device includes an electro-optic panel, a transparent protective member disposed at a viewer side of the electro-optic panel, an adhesive provided between the electro-optic panel and the transparent protective member, and a gas barrier film provided on a surface of the transparent protective member at a side opposite to the viewer side.

Claims

1. An electro-optic device comprising:

an electro-optic panel;

a transparent protective member disposed at a viewer side of the electro-optic panel;

an adhesive provided between the electro-optic panel and the transparent protective member; and

a gas barrier film provided on a surface of the transparent protective member at a side opposite to the viewer side.

2. The electro-optic device according to claim 1, wherein the gas barrier film is an inorganic film.

3. The electro-optic device according to claim 2, wherein the inorganic film includes one silicon oxide film and one aluminum oxide film.

4. The electro-optic device according to claim 2, wherein the inorganic film includes two silicon oxide films.

5. The electro-optic device according to claim 2, wherein the inorganic film includes two silicon oxide layers and one aluminum oxide layer.

6. The electro-optic device according to claim 4, wherein the aluminum layer is in contact with the transparent protective member and any one of the two silicon oxide films.

7. The electro-optic device according to claim 4, wherein one of the two silicon oxide films is a silicon dioxide film and is disposed at the electro-optic panel-side, and the other is a silicon monoxide film.

8. The electro-optic device according to claim 1, further comprising a touch-sensitive panel provided between the electro-optic panel and the transparent protective member, wherein the touch-sensitive panel is fixed to the transparent protective member with the gas barrier film and the adhesive therebetween.

9. An electronic apparatus comprising the electro-optic device according to claim 1.
