Abstract

In an electro-optical device, a backup plate is disposed to overlap an electro-optical panel, and the backup plate includes a groove portion (reinforcing groove) recessed from the front face and protruding on the back face. In addition, the backup plate includes a groove reinforcement region including the reinforcing member extending through inside of the groove portion. Accordingly, the backup plate is resistant to deflection, and therefore deflection of the electro-optical panel can be effectively suppressed.

Claims (27)

1. An electro-optical device comprising:

an electro-optical panel;

a backup plate disposed to overlap the electro-optical panel and including a groove portion recessed in a direction opposite to the electro-optical panel; and

a groove reinforcement region including a reinforcing member, the reinforcing member being fixed to the backup plate inside the groove portion and extending along the groove portion, such that a surface of the reinforcing member on the side of the electro-optical panel is located within a depth of the groove portion,

wherein the reinforcing member includes a frontal portion covering the opening of the groove portion on the side of the electro-optical panel, and a pair of side portions respectively superimposed on inner side walls of the groove portion opposing each other, and

wherein the reinforcing member is formed of a metal plate, and bent along the inner side walls in the groove reinforcement region.

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

wherein the backup plate includes a plurality of groove portions each of which oriented parallel to one of the sides of the electro-optical panel, and

at least one of the groove portions includes the reinforcing member to form the groove reinforcement region.

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

wherein at least a part of the groove reinforcement region includes a wiring member extending through inside of the groove reinforcement region.

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

wherein the wiring member is disposed inside the reinforcing member so as to extend along the groove reinforcement region.

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

wherein at least a part of the frontal portion of the reinforcing member includes a recessed portion receding from the frontal portion in a depth direction of the groove portion, and

a wiring member is disposed inside the recessed portion so as to extend along the groove reinforcement region.

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

wherein, in the groove reinforcement region, the groove portion includes a bottom portion formed on the side thereof protruding in a direction opposite to the electro-optical panel, and a member including a threaded hole open toward the bottom portion is fixed to the reinforcing member.

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

wherein the bottom portion includes an opening formed at a position corresponding to the threaded hole.

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

wherein the reinforcing member is formed of a resin member integrally with the backup plate so as to fill in the groove portion, in the groove reinforcement region.

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

wherein at least a part of the resin member includes a wiring member extending along the groove reinforcement region.

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

wherein, in the groove reinforcement region, the groove portion includes a bottom portion formed on the side thereof protruding in a direction opposite to the electro-optical panel, and the resin member includes a threaded hole open toward the bottom portion.

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