Liquid crystal projector comprising a plurality of light shielding members fixed between the lens array and the polarized light generator

Abstract

Heat generation is inhibited in a polarized light generating optics system in a projector. A liquid crystal projector includes: lens arraysthat generate partial light beams from a light beam emitted from a light source; and a polarized light generating optics systemthat generates polarized light, which is to be supplied to liquid crystal light valves, from the partial light beams. The polarized light generating optics systemseparates s-polarized light and p-polarized light by polarization separating films. The s-polarized light is reflected from reflecting filmsand is emitted directly. The p-polarized light is converted into s-polarized light by a selective phase difference plateand is emitted therefrom. The polarized light generating optics systemis equipped with light shielding surfacesthat shield light from entering into the reflecting films. The lens arraysare also equipped with light shielding membersthat act similarly as the light shielding surfaces. Disposing the light shielding memberscan inhibit heat generation on the light shielding surfaces
