Abstract:
1. A projector comprising: a reflection-type polarizing plate which separates entering luminous flux by polarization into first linearly polarized light and second linearly polarized light whose polarization directions cross each other at right angles; a reflection-type light modulation device disposed inclined to the reflection-type polarizing plate, the reflection-type light modulation device including a reflection-type liquid crystal panel to modulate the first linearly polarized light separated by polarization by the reflection-type polarizing plate according to image information and emit the modulated first linearly polarized light toward the reflection-type polarizing plate, and the reflection-type light modulation device including a heat sink that is attached to a back surface of the reflection-type liquid crystal panel; a supporting body which supports the reflection-type polarizing plate and the reflection-type light modulation device; a light shielding member disposed in an area to receive the second linearly polarized light which enters the reflection-type polarizing plate before modulation by the reflection-type light modulation device and is separated by polarization, and the light shielding member is connected with the supporting body; and a plurality of fins provided on a surface of the light shielding member that receives the second linearly light from the reflection-type polarization plate, the plurality of fins provided to face the reflection-type polarization plate.
