Image display apparatus

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;
• a projection optical system for projecting image light components combined by said color combination optical system on a surface on which projection is performed;
• and
• an outer box for housing said condensing optical system, said color separation optical system, said plurality of image display devices, said color combination optical system and said projection optical system,
• wherein a wall surface closest to said condensing optical system and said color separation optical member substantially perpendicular to an optical axis direction of said projection optical system in said outer box extends parallel along to a portion, which is farthest from said projection optical system, of the outer periphery of converging light incident on said color separation optical member from said condensing optical system.
