摘要：
A heat-conductive frame (448) is provided extending between a holder frame (446) and a fixing member (447) of an optical device (44). Additionally, a heat-conductive member (450) is provided, which abuts on a dust-proof glass on the light-irradiation side of a liquid crystal panel (440) and the fixing member (447). The holder frame (446) and the fixing member (447) are fixed by a heat-conductive agglutinate. Besides, a heat-conductive member (452) is attached extending between a light-irradiation surface of a transparent member (443A) of an irradiation-side polarization plate (443) and the fixing member (447). A heat-radiation fin (449) having a plurality of fin members (449B) is attached to an upper plate body (447C) of the fixing member (447).
