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.
