Abstract
A support member ( ) for supporting liquid crystal panels ( R, G, B) is disposed parallel to a cooling air flow channel formed between a light-incident end of a cross dichroic prism ( ) and the respective liquid crystal panels and is constructed by a pair of components for supporting a neighborhood of the ends of the respective liquid crystal panels, so that the gap between the light-incident end of the cross dichroic prism and the respective liquid crystal panels facing the cooling air flow channel can be enlarged, thereby flowing cooling air sufficient for cooling a polarizer ( ) and the respective liquid crystal panels in a direction of the cooling air flow channel for efficiently cooling them.
