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 (40)

1. An electro-optical device comprising:

a frame including a side plate; and

an electro-optical panel that is housed in an inner side of the side plate, the electro-optical panel including

a first side, a second side, a third side, and a fourth side, the first side opposing the third side, and the second side opposing the fourth side,

wherein the side plate includes a first facing surface that faces a part of a side surface of the electro-optical panel,

wherein an insulation member includes a second facing surface that faces the side plate,

wherein the second facing surface of the insulation member is in direct contact with the first facing surface of the side plate, the first facing surface facing the side surface of the electro-optical panel, and

wherein the insulation member is in direct contact with:

a polarizing plate disposed on a top surface of a viewing side of the electro-optical panel; and

a polarizing plate disposed on a bottom surface opposite to the viewing side of the electro-optical panel.

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

wherein a top portion of the side plate is in contact with a cover glass and is higher than the electro-optical panel.

3. The electro-optical device according to claim 1 , wherein the side plate is exposed in an edge of the frame.

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

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

wherein the driving circuit drives the electro-optical panel, and provided on an extension part of a second substrate that extends beyond areas of a first substrate and a liquid crystal layer, and

wherein the protection member is connected to the side plate of the frame.

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

6. The electronic apparatus according to claim 5 , further comprising a casing that houses the electro-optical device,

wherein the electro-optical device is brought into contact with the casing through the side plate.

7. The electro-optical device according to claim 2 ,

wherein an edge of the side plate, outside of the first facing surface, is bent toward the cover glass, and toward opposite the insulation member, to a position lower than the cover glass.

8. The electro-optical device according to claim 7 ,

wherein a driving circuit is disposed in an extension part of the electro-optical panel, and provided on an extension part of the second substrate that extends beyond areas of the first substrate and a liquid crystal layer, and

wherein the electro-optical panel further comprises a conduction sheet that covers the driving circuit and is electrically connected to the edge of the side plate bent toward the cover glass to the position lower than the cover glass.

9. The electro-optical device according to claim 1 , wherein the frame further includes a first side part that is formed by bending the side plate and a second side part that is formed by bending the side plate a second time away from the electro-optical panel side.

10. The electro-optical device according to claim 9 ,

wherein a resin part may be disposed on corners of the frame, and

wherein an upper edge of the side plate bent between the first side part and the second side part is flush with an upper surface of the resin part.

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

wherein the side plate includes a bottom part and four sides that rise from the bottom part, and

wherein each of three of the sides include a facing part that faces a part of the side surface of the electro-optical panel.

12. The electro-optical device according to claim 11 ,

wherein the second substrate includes an extension part having a driving circuit mounted thereon, the extension part extending beyond areas of the first substrate and a liquid crystal layer.

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

wherein a driving circuit is disposed in an extension part of the electro-optical panel, and provided on an extension part of the second substrate that extends beyond areas of the first substrate and a liquid crystal layer,

wherein the electro-optical panel further includes:

a conduction sheet that covers the driving circuit and is electrically connected to the edge of the side plate bent toward a cover glass to the position lower than the cover glass; and

an adhesive tape that is formed of an insulation material and disposed between the driving circuit and the conduction sheet, and

wherein the conduction sheet and the driving circuit are insulated from each other by the adhesive tape.
