Abstract

An electro-optical device includes an electro-optical panel, a frame, and an adhesion base. The panel includes a substrate holding an electro-optical material, a side of the electro-optical panel for displaying an image having a display area and a non-display area. The frame holds the electro-optical panel and has a side wall disposed in correspondence with at least a side surface of the electro-optical panel. An adhesion base has a form extending continuously at least from the non-display area to the side wall and is adhered to the non-display area and the side wall.

Claims

1. An electro-optical device comprising:

an electro-optical panel including a display side for displaying an image having a display area and a non-display area and a side surface;

a frame holding the electro-optical panel and having a first side wall disposed in correspondence with at least the side surface of the electro-optical panel; and

an adhesion base extending continuously at least from the non-display area to the first side wall, the adhesion base being adhered to the non-display area and the first side wall.

2. The electro-optical device according to claim 1, wherein the frame further having a second side wall being disposed in correspondence with another side surface of the electro-optical panel and opposing the first side wall with the non-display area being disposed therebetween.

3. The electro-optical device according to claim 1, wherein the electro-optical panel includes a first substrate and a second substrate opposing each other with the electro-optical material being disposed therebetween, the second substrate having a protrusion that is extends beyond the first substrate and on which an integrated circuit for driving an electro-optical material is mounted, the protrusion is in the non-display area, the adhesion base extends continuously at least from the protrusion to the first side wall, the adhesion base is adhered to the protrusion and the first side wall.

4. The electro-optical device according to claim 3, wherein the frame further having a second side wall being disposed in correspondence with another side surface of the electro-optical panel and opposing the first side wall with the protrusion being disposed therebetween.

5. The electro-optical device according to claim 4, wherein the frame has a bottom side that is continues from the first and second side walls, the bottom has a surface facing away from the electro-optical panel, the adhesion base extends at least from the first side wall to the surface of the bottom side and is adhered to the surface of the bottom side.

6. The electro-optical device according to claim 4, wherein the adhesion base extends to the second side wall from the protrusion and is adhered to the second side wall.

7. The electro-optical device according to claim 4, further comprising another adhesion base, wherein the protrusion has a first area disposed adjacent the first side wall and a second area disposed adjacent the second side wall, and wherein the adhesion base extends continuously at least from the first area to the first side wall and is adhered to the first area and the first side wall, the other adhesion base extends continuously at least from the second area to the second side wall and is adhered to the second area and the second side wall.

8. The electro-optical device according to claim 3, wherein the protrusion has a side opposite to another side where the integrated circuit is mounted, the adhesion base is a light-shielding member which is adhered to the side of the protrusion and which intercepts light propagating towards the integrated circuit.

9. The electro-optical device according to claim 3, further comprising a flexible circuit board electrically connected to the electro-optical panel, wherein the adhesion base is an extending portion extending from the flexible circuit board.
