Abstract

An electro-optical device includes a frame including a conduction part and a resin part, an electro-optical panel that is housed in the inner side of the resin part, and an exposure part that is formed by exposing the conduction part from the resin part. The exposure part is disposed to face at least a part of an end face of the electro-optical panel or protrude from a surface of the electro-optical panel over the end face.

Claims

1. An electro-optical device comprising:

a frame including a conduction part and a resin part;

an electro-optical panel that is housed in the inner side of the resin part; and

an exposure part that is formed by exposing the conduction part from the resin part,

wherein the exposure part is disposed to face at least a part of an end face of the electro-optical panel or protrude from a surface of the electro-optical panel over the end face.

2. The electro-optical device according to claim 1, wherein the conduction part is exposed in an edge of the frame.

3. The electro-optical device according to claim 1,

wherein the conduction part is a metal plate disposed at least along the end face of the electro-optical panel, and

wherein the resin part includes a resin material that is formed integrally with the metal plate.

4. The electro-optical device according to claim 3,

wherein the frame includes a bottom part including the metal plate and a side part that is formed by bending the metal plate to the electro-optical panel side, and

wherein the resin part is integrally formed with the metal plate in the side part.

5. The electro-optical device according to claim 3,

wherein the frame is formed by insert-molding the metal plate into the resin material.

6. The electro-optical device according to claim 1, wherein a gap is formed between the frame and the end face of the electro-optical panel.

7. The electro-optical device according to claim 6, wherein a conduction member having conductivity higher than a substrate of the surface of the electro-optical panel is filled in the gap.

8. The electro-optical device according to claim 4, wherein an edge of the metal plate is bent in the side part toward a side opposite to the electro-optical panel.

9. The electro-optical device according to claim 4, wherein an edge of the metal plate is bent in the side part toward the electro-optical panel side.

10. The electro-optical device according to claim 1, further comprising:

a driving circuit that drives the electro-optical panel; and

a conductive protection member that covers at least a part of the driving circuit,

wherein the protection member is connected to the conduction part of the frame.

11. An electronic apparatus comprising the electro-optical device according to claim 1.

12. The electronic apparatus according to claim 11, further comprising a casing that houses the electro-optical device,

wherein the electro-optical device is brought into contact with the casing through the conduction part.
