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 (18)

1. An electro-optic device, comprising:

a polarizing plate;

a first substrate;

a second substrate opposed to the first substrate;

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

a dust-proof plate located on an opposite side of one of the first and second substrates than the electro-optic substance; and

an anti-reflection film disposed at a position between the dust-proof plate and the polarizing plate.

2. The electro-optic device according to claim 1 , the anti-reflection film including a plurality of layers.

3. The electro-optic device according to claim 1 , further comprising a coating member located to the opposite side of the anti-reflection film than one of the first and second substrates.

4. An electro-optic device, comprising:

a polarizing plate;

a first substrate;

a second substrate opposed to the first substrate;

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

a dust-proof plate located on an opposite side of the first substrate than the electro-optic substance; and

an anti-reflection film disposed at a position between the dust-proof plate and the polarizing plate.

5. The electro-optical device according to claim 4 , the anti-reflection film including a plurality of layers.

6. The electro-optical device according to claim 4 , further comprising a coating member located on the opposite side of the anti-reflection film than one of the first and second substrates.
