Embodiment Construction

[0054] Embodiments of the present invention will be described below with reference to the drawings.

[0055] (Embodiment of projection type liquid crystal device)

[0056] First, refer to figure 1 , the embodiment of the projection type liquid crystal device of the present invention will be described focusing on the 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.

[0057] exist figure 1 Among them, the liquid crystal projector 1100 as an example of the multi-plate type color projector of this embodiment is three liquid crystal light valves including an electro-optical device in which a driving circuit is mounted on a TFT array substrate. A projector constructed for use with 100G and 100B.

[0058] In the liquid crystal projector 1100, if the lighting unit 1102,...

Abstract

The invention provides a technique to effectively cool an electro-optical device in the electro-optical device encased in a mounting case. The mounting case can include a plate member arranged so as to face one surface of a liquid crystal panel and a cover member arranged so as to cover the plate and the liquid crystal panel. Cooling-air guiding portions that include at least some of the side surfaces of the liquid crystal panel as at least some of the surfaces that constitute the passage can be provided in the cover member.

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...
