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 (10)

1. An electro-optic device comprising:

an electro-optic panel;

a transparent protective member disposed at a viewer side of the electro-optic panel, the transparent protective member being composed of plastic;

a polarizer provided between the electro-optic panel and the transparent protective member;

a first adhesive having a thickness ranging from 25 μm to 50 μm and provided between the electro-optic panel and the polarizer;

a gas barrier layer that is provided at a side opposite to the viewer side of the transparent protective member, and disposed in direct contact with the transparent protective member, wherein the gas barrier layer includes a three-layered inorganic film in which an Al 2 O 3 layer having a thickness ranging from 25 nm to 45 nm directly contacting the transparent protective member, a SiO layer having a thickness ranging from 15 nm to 45 nm, and a SiO 2 layer having a thickness ranging from 100 nm to 150 nm are laminated in this order; and

a second adhesive having a thickness ranging from greater than 25 μm to 400 μm and provided between the gas barrier layer and the polarizer, the second adhesive having a thickness greater than that of the first adhesive,

wherein the SiO 2 layer directly contacts the second adhesive.

2. The electro-optic device according to claim 1 , further comprising a touch-sensitive panel provided between the electro-optic panel and the gas barrier layer.

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