ABSTRACT:
A projector includes: a lighting device which emits illumination light; a liquid crystal panel which modulates the illumination light emitted from the lighting device according to image information; a projection system which projects light modulated by the liquid crystal panel; a polarization plate which is disposed at least either on the light incident side or the light exit side of the liquid crystal panel and has at least a polarization layer; a liquid crystal panel side light-transmissive substrate affixed to the liquid crystal panel side surface of the polarization plate and made of inorganic material; and an opposite side light-transmissive substrate affixed to the surface of the polarization plate on the side opposite to the liquid crystal panel side surface of the polarization plate. The thickness of the liquid crystal panel side light-transmissive substrate is smaller than the thickness of the opposite side light-transmissive substrate.
