Abstract

The invention provides an electro-optical device that displays high quality images regardless of temperature circumstances of the surroundings. The electro-optical device can be encased in a mounting case which accommodates a liquid crystal panel in which projection light is incident on an image display region from a light source. The mounting case can include a plate arranged so as to face one surface of the liquid crystal panel, a cover arranged so as to cover the plate and the liquid crystal panel, an adhesive for attaching the plate to the liquid crystal panel, and adhesive pockets provided in at least one of the plate and the cover, for accommodating the adhesive.

Claims (30)

1. An electro-optical device comprising:

an electro-optical panel;

a plate that faces one surface of the electro-optical panel;

a cover that covers the plate and the electro-optical panel; and

at least one adhesive that attaches the plate to the electro-optical panel, the plate including at least one bent portion with a surface that confronts a side surface of the electro-optical panel, the bent portion connecting at least one concave adhesive pocket, which is bent away from the side surface of the electro-optical panel.

2. The electro-optical device according to claim 1 , the plate including a flat portion that is quadrangular in plan view and the at least one bent portion, which is located on a side of the flat portion, and

the adhesive pocket protruding toward an outside of the flat portion.

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

two of the adhesive pockets being provided on both sides of the bent portion.

4. The electro-optical device according to claim 1 , the adhesive comprising a photo-curing resin.

5. A projection type display device, comprising:

the electro-optical device according to claim 1 ;

a light source that emits light;

an optical system that guides light onto the electro-optical device; and

a projection optical system that projects the light emitted from the electro-optical device.

6. The electro-optical device according to claim 1 , wherein the adhesive attaches the plate to a side surface of the electro-optical panel, two of the adhesive pockets being provided on the plate at positions facing opposite side surfaces of the electro-optical panel, the adhesive pockets being open at a side of the plate that faces the cover.

7. A mounting case for accommodating an electro-optical panel having an image display region on which projection light from a light source is incident, the mounting case comprising:

a plate that faces one surface of the electro-optical panel;

a cover that covers the plate and the electro-optical panel;

a plate that faces one surface of the electro-optical panel;

a cover that covers the plate and the electro-optical panel;

at least one adhesive that attaches the plate to the electro-optical panel; and

adhesive pockets that accommodate the adhesive, which are provided on both sides of the plate.

at least one adhesive that attaches the plate to the electro-optical panel; and

adhesive pockets that accommodate the adhesive, which are provided on both sides of the plate.

8. An electro-optical device comprising:

an electro-optical panel having two broad surfaces on opposite sides thereof and a side surface extending substantially perpendicular to at least one of the broad surfaces;

a plate including a side surface that confronts the side surface of the electro-optical panel, the side surface including an inner side surface facing the side surface of the electro-optical panel and an outer side surface facing away from the side surface of the electro-optical panel, the inner side surface including a concave adhesive pocket that recedes away from the side surface of the electro-optical panel compared with other portions of the inner side surface;

a cover having a portion that confronts the outer side surface of the plate; and

adhesive that attaches the plate to the electro-optical panel, a portion of the adhesive being located in the concave adhesive pocket.
