ABSTRACT:
A projection displaying apparatus projects on a projection plane an image displayed on a reflection displaying device using light emitted from a light source. The projection displaying apparatus includes a wind feeding portion for feeding a cooling wind to a light-incident side of a polarization plate disposed on an optical path from the light source to the reflection displaying device, and a wind guiding portion for guiding the cooling wind such that the cooling wind can be blown on the polarization plate slantingly relative to a light-incident face of the polarization plate.
