Abstract

An electro-optical device includes a pair of substrates arranged so as to face each other, an electro-optical material layer interposed between the pair of substrates, a through hole penetrating through the pair of substrates and the electro-optical material, and a encapsulating member disposed in the through hole for sealing the electro-optical material layer while being disposed between the pair of substrates, in which the encapsulating member is disposed closer to the electro-optical material layer than an outer surface of a display substrate of the pair of substrates and outside an entrance portion of the through hole, in a plan view, the entrance portion being on an outer surface side of the display substrate.

Claims (19)

1. An electro-optical device, comprising:

a pair of substrates arranged so as to face each other;

an electro-optical material layer interposed between the pair of substrates;

a through hole penetrating through the pair of substrates and the electro-optical material; and

an encapsulating member disposed in the through hole for sealing the electro-optical material layer while being disposed between the pair of substrates;

wherein the encapsulating member is disposed closer to the electro-optical material layer than an outer surface of a display substrate of the pair of substrates and outside an entrance portion of the through hole, in a plan view, the entrance portion being on an outer surface side of the display substrate.

2. The electro-optical device according to claim 1 , wherein a surface of the through hole is rough.

3. The electro-optical device according to claim 1 , wherein the encapsulating member penetrates through one substrate other than the display substrate of the pair of substrates.

4. The electro-optical device according to claim 1 , wherein the encapsulating member is disposed closer to the electro-optical material layer than an outer surface of one substrate other than the display substrate of the pair of substrates.

5. The electro-optical device according to claim 1 , wherein the electro-optical material layer is an electrophoretic layer having a plurality of capsules, each containing colored particles which can cause an electrophoretic reaction and a dispersion medium for dispersing the colored particles therein.

6. A method of manufacturing an electro-optical device having a pair of substrates arranged so as to face each other and an electro-optical material layer interposed between the pair of substrates, comprising:

arranging the pair of substrates so as to face each other,

forming a continuous hole so as to link the pair of substrates and the electro-optical material layer with each other but not link part of a display substrate, which is on a display surface side of the display substrate, of the pair of substrates;

sealing the electro-optical material layer in the continuous hole; and

forming a through hole having a diameter smaller than that of the continuous hole at a region where the continuous hole is provided so as to penetrate through the pair of substrates and the electro-optical material layer.

7. The method of manufacturing an electro-optical device according to claim 6 , wherein the continuous hole is formed by forming a first concave in the display substrate in a manner such that the first concave terminates at a midway portion of the display substrate so as to leave part of the display substrate on the display surface side thereof unpenetrated, forming a second concave in one substrate other then the display substrate in a manner such that the second concave terminates at a midway portion of the substrate so as to leave part of the substrate on an outer surface side of the substrate unpenetrated, the outer surface not being a surface on which the electro-optical layer is formed, and arranging the pair of substrates in a manner such that the first concave and the second concave face each other.

8. The method of manufacturing an electro-optical device according to claim 6 , wherein the continuous hole is formed so as to penetrate through the substrate other than the display substrate of the pair of substrates.

9. The method of manufacturing an electro-optical device according to claim 6 , wherein the electro-optical material layer is a liquid crystal layer, and is provided between the pair of substrates after formation of the through hole.

10. An electronic apparatus on which the electro-optical device according to claim 1 or the electro-optical device manufactured by the manufacturing method according to claim 6 is mounted.
