Abstract

In at least one embodiment of the disclosure, an electro-optical device includes an electro-optical panel including a display area. The electro-optical panel has an incidence face side that faces incident light from a light source and an opposite side which is opposite to the incidence face side. A holding member houses the electro-optical panel. A heat radiation member is provided at the opposite side of the electro-optical panel. A light-shielding plate is formed so as to at least partially surround the display area of the electro-optical panel. The light-shielding plate is provided so as to make contact with the holding member and the incidence face side of the electro-optical panel.

Claims (16)

1. An electro-optical device comprising:

an electro-optical panel including a display area, the electro-optical panel having an incidence face side that faces incident light from a light source and an opposite side which is opposite to the incidence face side;

a holding member which houses the electro-optical panel;

a heat radiation member provided at the opposite side of the electro-optical panel; and

a light-shielding plate formed so as to at least partially surround the display area of the electro-optical panel and provided so as to make contact with the holding member and the incidence face side of the electro-optical panel.

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

the holding member includes an attaching portion and a concave portion, the attaching portion formed so as to protrude toward a mounted member side and away from the light-shielding plate, and the concave portion provided so as to be concave as compared to the attaching portion, and

the light-shielding plate is disposed so as to come into contact with the concave portion.

3. The electro-optical device according to claim 1 , further comprising a hook member extending from a back side of the heat radiation member toward the electro-optical panel, the hook member fixing the heat radiation member to the holding member.

4. The electro-optical device according to claim 1 , wherein an opening portion of the light-shielding plate is formed inside an opening portion of the holding member as viewed from the incidence face side.

5. The electro-optical device according to claim 1 , wherein the light-shielding plate has elasticity.

6. The electro-optical device according to claim 1 , wherein the heat radiation member is formed integrally with the holding member.

7. The electro-optical device according to claim 1 , wherein the holding member further includes an extending portion formed integrally with the holding member, the extending portion extending beyond a front side of the heat radiation member and toward a back side of the heat radiation member.

8. The electro-optical device according to claim 3 , wherein the hook member includes an opening portion and the holding member includes a convex portion, and the heat radiation member and the holding member are fixed to each other by the opening portion being engaged with the convex portion.

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

10. The electro-optical device according to claim 9 , wherein the electronic apparatus is a liquid crystal projector.
