Abstract

An electro-optical device is provided which includes a first electro-optical panel, an electronic part that is provided to be adjacent to the first electro-optical panel, a receiving part that is interposed between the first electro-optical panel and the electronic part and receives the first electro-optical panel and the electronic part, a first metal frame that fixes the first electro-optical panel to the receiving part, and a second metal frame that fixes the electronic part together with the first metal frame therebetween. In the electro-optic device, any one of the first and second metal frames is extended toward the other one and has an elastic conductive part, and the conductive part is pressed against the other one by the elastic force and comes into contact with the other one such that the first and second metal frames are electrically connected to each other.

Claims (31)

1. An electro-optical device comprising:

a first electro-optical panel;

an electronic part that is provided adjacent to the first electro-optical panel;

a receiving part that is interposed between the first electro-optical panel and the electronic part and that receives the first electro-optical panel and the electronic part;

a first metal frame that fixes the first electro-optical panel to the receiving part; and

a second metal frame that fixes the electronic part, the first and the second metal frames sandwiches the receiving part therebetween,

wherein one of the first and second metal frames has an elastic conductive part that extends toward the other one of the first and second metal frames, and

the conductive part is pressed against the other one of the first and second metal frames by the elastic force and comes into contact with the other one of the first and second metal frames such that the first and second metal frames are electrically connected to each other.

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

a circuit board that is electrically connected to the first electro-optical panel,

wherein the conductive part extends from the circuit board side or the opposite side of the circuit board side of the one of the first and second metal frames toward the other one of the first and second metal frames.

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

wherein the conductive part is a spring.

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

wherein each of the first and second metal frames has a sidewall that is extended to each other, and

the spring is extended from the sidewall of the one of the first and second metal frames to overlap and comes into contact with the sidewall of the other one of the first and second metal frames such that the first and second metal frames are electrically connected to each other.

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

wherein the sidewall of the other one of the first and second metal frames has a recess, which receives at least the spring, on an inner side or an outer side of the other sidewall, and

the spring is received in the recess to come into contact with a sidewall of the recess.

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

wherein the conductive part includes a plurality of springs which are extended from the sidewall of the one of the first and second metal frames.

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

wherein the spring is a plate spring that bends toward the sidewall of the other one of the first and second metal frames.

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

wherein a part of the sidewall of the one of the first and second metal frames extends toward the other one of the first and second metal frames, the spring is a plate spring which is formed by cutting and bending the extended part from the sidewall of the one of the first and second metal frames.

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

wherein the electronic part is a soundgenerating unit.

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

wherein the electronic part is a second electro-optical panel, and

a display side of the second electro-optical panel and a display side of the first electro-optical panel are facing opposite direction.

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