ABSTRACT:
This invention provides a technique of reducing temperature rise due to heat generation of polarization control elements. A projector includes: an illumination optical system; 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 a plurality of optical components arranged on an optical path from the illumination optical system to the projection optical system. At least one of the plurality of optical components is a polarization control component that includes: a polarization control element including organic material for the 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. The light-transmissive member and the base frame are thermally coupled.
