Provided is a liquid crystal projector which prevents deterioration of an aluminum grid inorganic polarizing plate due to dusts included in cooling wind for cooling a liquid crystal panel module. A shade member is provided along a surface of the inorganic polarizing plate on which the cooling wind is received, to prevent the surface from being directly receiving the cooling wind and thus prevent attachment of dusts. In order to reduce a cooling effect due to the shade member, 0.9t@a@1.5t and 0.5t@b@1.5t are satisfied, where a represents a width of the shade member, b represents a distance between the shade member and the polarizing plate, and t represents a thickness of the polarizing plate. As a result, it is possible to obtain the cooling effect and the effect of reducing the dusts at the same time. |
