Abstract

A liquid crystal device includes an element substrate, a counter substrate, a liquid crystal disposed between the substrates, a sealing material disposed in the spacing between the element substrate and the counter substrate and sealing the liquid crystal, a gas barrier layer disposed outside of the sealing material to cover the outside of the spacing and having a portion located in the spacing, and an gap region defined in at least a portion of the space between the sealing material and the gas barrier layer.

First claim

What is claimed is:

1. An electro-optical device, comprising:
a first substrate;
a second substrate;
an electro-optical substance disposed between the first substrate and the second substrate;
a sealing material disposed in a spacing between the first substrate and the second substrate and surrounding a periphery of the electro-optical substance;
a moistureproof resin layer disposed outside of the sealing material and having a portion located in the spacing, the portion located in the spacing having a concave curved surface; and
a gap region defined in at least a portion of a space between the sealing material and the moistureproof resin layer,
wherein
the moistureproof resin layer contacts a first substrate inner surface that faces the second substrate, a second substrate inner surface that faces the first substrate, and a first portion of the sealing material, such that the gap region is defined between the moistureproof resin layer and a second portion of the sealing material that does not contact the moistureproof resin layer, and
the gap region is only disposed midway between the first substrate and the second substrate such that the moisture proof resin layer is disposed both between the gap region and the first substrate inner surface and between the gap region and the second substrate inner surface.

2. The electro-optical device according to claim 1 , further comprising an inorganic film layer disposed outside of the moistureproof resin layer and at least partially in contact with the outer surface of the moistureproof resin layer.

3. The electro-optical device according to claim 2 , wherein the moistureproof resin layer includes at least one of a one-part photocurable resin, a photo- and heat-curable resin and a two-part cold-curable resin, and is electrically insulating.

4. The electro-optical device according to claim 3 , wherein the moistureproof resin layer includes an epoxy resin or a modified epoxy resin.

5. The electro-optical device according to claim 2 , wherein the inorganic film layer has a film thickness of not less than 0.1 μm and not more than 2.5 μm.

6. The electro-optical device according to claim 2 , wherein the inorganic film layer includes aluminum or chromium.

7. An electronic apparatus comprising the electro-optical device of claim 2 .

8. An electronic apparatus comprising the electro-optical device of claim 1 .
