PROBLEM TO BE SOLVED: To provide a structure for fitting a liquid crystal panel to a prism which can improve cooling performance more. SOLUTION: A
storage body holds a holding frame 443 which is fixed to a pedestal 445 and holds the liquid crystal panel 441R and has on its light incidence side raised pieces 446D, forming a space for receiving the holding frame 443, projected to both the right and left sides and on its light
projection side projection parts 446F for forming an air passage with a cross
dichroic prism 45 formed on both the right and left sides; and the liquid crystal panel 441R is fitted to the cross dichroic prism 45 through a holding member 446 having an opening part 446B at the part
corresponding to the panel surface of the liquid crystal panel 441R. 主权项：
