Abstract
A liquid crystal panel unit and a liquid crystal projector incorporating the liquid crystal panel unit. The panel includes a metallic sealed container with a light-transmissive window, a liquid crystal panel accommodated in the sealed container so as to allow light being transmitted to leave the light-transmissive window, and a fan accommodated in the sealed container so as to be spaced from the liquid crystal panel. The liquid crystal panel unit can reliably cool the liquid crystal panel, without any deterioration in the image quality due to dust. A liquid crystal projector using the liquid crystal panel unit is also provided.
