Abstract

The invention provides, an electro-optic device that can include a pair of substrates sandwiching an electro-optic substance therebetween. The electro-optic device can further include a coating member including an antistatic material and being disposed on a surface not opposing the electro-optic substance of at least one of the pair of substrates. Accordingly, problems of dust adhesion on the surface of the electro-optic device and dust projection can be solved so as to enable images with high quality to be displayed.

Claims (24)

1. An electro-optic device, comprising:

a first substrate;

a second substrate;

an electro-optic substance sandwiched between the first and second substrates;

a first zirconia layer located on the opposite side of the first substrate from the electro-optic substrate;

a silica layer located on the opposite side of the first zirconia layer from the first substrate;

a transparent conductive layer located on the opposite side of the silica layer from the first zirconia layer, the transparent conductive layer being formed from a transparent conductive material; and

a second zirconia layer located on the opposite side of the transparent conductive layer from the silica layer.

2. An electro-optic device, comprising:

a first substrate;

a second substrate;

an electro-optic substance sandwiched between the first and second substrates; and

an anti-reflection coating located on the opposite side of the first substrate from the electro-optic substance, the anti-reflection coating including a transparent conductive layer sandwiched between two other layers made from anti-static materials.

3. The electro-optic device according to claim 2 , wherein an outermost layer of the anti-reflection coating being zirconia.

4. The electro-optic device according to claim 2 , wherein the transparent conductive layer being located between a zirconia layer and a silica layer.
