ABSTRACT:
A projector apparatus includes a color separation optical system which separates illumination light into color light components, image forming panels illuminated with the color light components, respectively, a color synthesis optical system which synthesizes the light components from the illuminated image forming panels, and a projecting optical system which projects light from the color synthesis optical system. Transparent substrates are arranged on at least one of incident and exit surface side of the image forming panels. Each of the transparent substrates holds a polarizer. A surface area of at least one of the transparent substrates is larger than those of the remaining transparent substrates.
