Abstract

An electro-optical device includes: an electro-optical panel; a light-transmissive member that overlaps the electro-optical panel and has a protruding part that protrudes so as to be positioned outside an edge of the electro-optical panel, the light-transmissive member having a first area and a second area that is located outside the first area; a coloration layer that is formed on a surface of the light-transmissive member at the second area; an adhesive material that is provided between a part of the coloration layer and a corresponding part of the electro-optical panel as well as between the part of the light-transmissive member and a corresponding part of the electro-optical panel; and a first light-shielding layer formed over one surface of the light-transmissive member, and the first light-shielding layer being formed at an area where the coloration layer does not overlap the adhesive material in a plan view.

Claims (23)

1. An electro-optical device comprising:

an electro-optical panel that has an effective display area;

a light-transmissive member that overlaps the electro-optical panel in a plan view and has a protruding part that protrudes so as to be positioned outside an edge of the electro-optical panel, the light-transmissive member having a first area that corresponds to the effective display area of the electro-optical panel and a second area that is located outside the first area;

a coloration layer that is formed on a surface of the light-transmissive member at the second area;

an adhesive material that is provided between a part of the coloration layer and a corresponding part of the electro-optical panel as well as between the first-area part of the light-transmissive member and a corresponding part of the electro-optical panel so as to offer tight adhesive contact therebetween; and

a first light-shielding layer formed over one surface of the light-transmissive member, the surface facing the electro-optical panel, and the first light-shielding layer being formed at an area where the coloration layer does not overlap the adhesive material in a plan view.

2. The electro-optical device according to claim 1 , wherein the electro-optical panel includes a second light-shielding layer that is formed at an area so as to overlap the coloration layer when viewed in plan.

3. The electro-optical device according to claim 1 , further comprising an illumination device that is provided at one surface side of the electro-optical panel that is opposite to the other surface side thereof that faces toward the light-transmissive member and/or is closer to the light-transmissive member than the one surface side, the illumination device being provided with a light source.

4. The electro-optical device according to claim 3 , wherein the illumination device includes a third light-shielding layer that is formed at an area so as to overlap the coloration layer when viewed in plan.

5. The electro-optical device according to claim 2 , wherein the first light-shielding layer and the second light-shielding layer partially overlap each other when viewed in plan.

6. The electro-optical device according to claim 4 , wherein the first light-shielding layer and the third light-shielding layer partially overlap each other when viewed in plan.

7. The electro-optical device according to claim 2 , wherein the electro-optical panel includes a pair of substrates and an electro-optical material that is sandwiched between the pair of substrates; and the second light-shielding layer is formed on at least one of the pair of substrates.

8. The electro-optical device according to claim 1 , wherein the light-transmissive member is a light-transmissive protection plate that protects the electro-optical panel against an external force, which is applied from the outside.

9. The electro-optical device according to claim 1 , wherein the light-transmissive member is a touch panel.

10. The electro-optical device according to claim 1 , wherein the light-transmissive member includes a touch panel and a light-transmissive protection plate that protects the touch panel against an external force, which is applied from the outside.

11. An electronic apparatus that is provided with the electro-optical device according to claim 1 , the electro-optical device functioning as a display section of the electronic apparatus.

12. An electronic apparatus comprising:

the electro-optical device according to claim 3 ;

a frame that supports a peripheral edge part of the light-transmissive member; and

another light source that is provided inside the frame,

wherein a gap is formed between the frame and the electro-optical panel;

another light source mentioned above is provided at a position corresponding to the gap; and

at least a part of the first light-shielding layer is provided at an area that at least covers the gap.
