Abstract:
A projection display device includes: a light modulator for modulating light from a light source; a polarizer disposed at a position facing the light modulator; a cooling section for allowing an air to flow in a space between the light modulator and the polarizer; and an air deflector for deflecting the air flowing in the space between the light modulator and the polarizer toward the polarizer.
