Abstract:
An image display apparatus, comprising:a condensing optical system for changing illumination light from a light source to converging light; a color separation optical system having a color separation optical member for reflecting a color light component in a specific wavelength range of said converging light and transmitting color light components in the other wavelength ranges; a plurality of image display devices illuminated by a plurality of color light components separated by said color separation optical system, respectively, a color combination optical system for combining image light components of a plurality of colors emanating from said plurality of image display devices; and a projection optical system for projecting image light components combined by said color combination optical system on a surface on which projection is performed, wherein an optical axis of light incident on said color separation optical member forms an angle smaller than 45 degrees with a normal to a light incident surface of said color separation optical member.
