Abstract

See full text

A liquid crystal projector which prevents deterioration of the aluminum grid inorganic polarizing plate due to dust in the cooling air for cooling the liquid crystal panel module. A shade member along the surface of the inorganic polarizing plate prevents the surface from being directly hit by the cooling wind and thus prevents dust from attaching to the surface of the plate.
