ABSTRACT:
A liquid crystal panel in which temperature rise of the liquid crystal panel is sufficiently restrained by cooling the panel by means of a cooling liquid, and exudation of the cooling liquid toward the liquid crystal material is prevented. Disclosed are cover members attached to the liquid crystal panel that form cavities on the light entrance and exit sides of the panel. The cover members are such that a sealed portion of the liquid crystal material is not in contact with the cavities. The cover members are light transmitting. The cavities are filled with the cooling liquid.
