Abstract: Aspects of the invention can provide a projector capable of projecting a high-quality image by illumination that does not produce a difference in size among illumination areas for respective colors including red, green, and blue. A light-source light from a light source can be separated into color lights by first and second dichroic mirrors provided in a color separation system, which independently go incident on corresponding liquid crystal light valves as illumination lights. Herein, a mutual chromatic aberration can be corrected by adjusting, as needed, the radii of curvature of respective field lenses provided in the color separation system for use in adjusting angles of incidence of illumination lights with respect to the liquid crystal light valves. This configuration makes it possible to illuminate the respective liquid crystal light valves by illumination areas of exactly the same size, which in turn enables a high-quality image having no display shadow to be projected.

Abstract: Heat generation is inhibited in a polarized light generating optics system in a projector. A liquid crystal projector includes: lens arrays 140, 150 that generate partial light beams from a light beam emitted from a light source; and a polarized light generating optics system 160 that generates polarized light, which is to be supplied to liquid crystal light valves, from the partial light beams. The polarized light generating optics system 160 separates s-polarized light and p-polarized light by polarization separating films 64a. The s-polarized light is reflected from reflecting films 64b and is emitted directly. The p-polarized light is converted into s-polarized light by a selective phase difference plate 66 and is emitted therefrom. The polarized light generating optics system 160 is equipped with light shielding surfaces 62b that shield light from entering into the reflecting films 64b.
