PROBLEM TO BE SOLVED: To contribute to the size reduction, higher luminance, and higher reliability of a projector by more improving the cooling performance of an optical modulation part composed of a liquid crystal panel, etc. SOLUTION: This projector is constituted by fitting a liquid crystal panel 40R which modulates light according to image information to a prism 20 which composites multiple color light; and the light-incidence side end surface of the liquid crystal panel 40R is fixed to a 1st transparent heat radiation plate 53, which is fixed to a prism 20 (where a 2nd heat radiation plate 54 is stuck upon occasion) across heat-conductive coupling members 56 and 57 arranged on both the side parts of the 1st transparent heat radiation plate while an air passage 59 is formed between the liquid crystal panel 40R and prism 20. |
