ABSTRACT:
The invention provides a structure to attach a liquid crystal panel to a prism, which enables further enhancements in cooling capabilities. The structure includes a storing member fixed on a base and holding a holding frame, where a liquid crystal panel is held. Erected pieces to form a space to receive the holding frame are formed protruding on both left and right sides at the light incident side. Protrusions to form an air path with a cross-dichroic prism are formed on both left and right sides on the light emitting side. The liquid crystal panel is attached to the cross-dichroic prism through a holding member having an opening at a portion corresponding to the panel face of the liquid crystal panel.
