Problems solved by technology

[0010] Then, since the force is applied to the liquid crystal panel due to the installation of the case, useless internal stress may be generated in the liquid crystal panel, or the gap between the liquid crystal cells between the transparent substrates may be partially narrowed.
As a result, it becomes difficult to display high-quality images due to color spots, etc., occurring on the image

Embodiment Construction

[0050] Embodiments of the present invention will be described below with reference to the drawings.

[0051] (Embodiment of Projective Liquid Crystal Device)

[0052] First, referring to FIG. 1, an embodiment of the projection liquid crystal device of the present invention will be described focusing on an optical system incorporated into the optical unit. The projection display device of this embodiment is constructed by a multi-plate type color projector composed of three liquid crystal light valves as an example of an electro-optic device with a mounting case.

[0053] In FIG. 1, a liquid crystal projector 1100, which is an example of a multi-panel color projector according to the present embodiment, includes three liquid crystal light valves including an electro-optical device with a driving circuit mounted on a TFT array substrate, each serving as light for RGB. A projector configured using the valves 100R, 100G, and 100B.

[0054] In the liquid crystal projector 1100, i...

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.

Description

technical field [0001] The present invention relates to a mounting case for mounting an electro-optical device such as a liquid crystal panel used as a light valve in a projection display device such as a liquid crystal projector, or a mounting case with a belt for mounting or accommodating the electro-optical device in the mounting case The technical field of the electro-optic device and the projection display device including such an electro-optic device with a mounting case. Background technique [0002] Generally, when a liquid crystal panel is used as a light valve of a liquid crystal projector, the liquid crystal panel is not installed in an exposed state in a frame constituting the liquid crystal projector, but is installed or accommodated in a suitable Installing in the casing and setting the liquid crystal screen with the installation casing in the above-mentioned frame body or the like. [0003] This is because the liquid crystal panel can be easily fixed to the a...
