PROBLEM TO BE SOLVED: To provide a structure to attach a liquid crystal panel to a prism, which enables further enhancements in cooling capabilities. SOLUTION: The structure includes a housing body fixed on a base 445 and holding a holding frame 443, where the liquid crystal panel 441R is held. Erected pieces 446D to form a space to receive the holding frame 443 are formed protruding on both right and left sides on the light incident side, and protrusions 446F to form an air path with a cross dichroic prism 45 are formed on both right and left sides on the light exiting side. The liquid crystal panel 441R is attached to the cross dichroic prism 45 through a holding member 446 having an opening 446B at a portion corresponding to the panel face of the liquid crystal panel 441R.
