Patent ID: 6935753

Claim:
A projector, comprising: an illumination optical system including a light source device; an electro-optical device for modulating light from the illumination optical system in response to image information; a projection optical system for projecting modulated light obtained with the electro-optical device; and a base frame, formed using material including metal material, for mounting all optical components arranged on an optical path from the illumination optical system to the projection optical system excluding the light source device, wherein at least one of the optical components is a polarization control component comprising: a polarization control element including organic material for controlling polarization state of light exiting from the polarization control element; and a light-transmissive member having a thermal conductivity of at least about 0.8 W/(m·K), to which the polarization control element is stuck, and wherein the light-transmissive member and the base frame are thermally coupled.
