Abstract:
A projector for displaying color images, comprising:an illumination optical system; a colored-light-separating optical system that separates light emitted from the illumination optical system into first, second, and third colored light corresponding to three color components, respectively; first, second, and third electro-optical devices which modulate the first, second, and third colored light, respectively, according to image data, and produce first, second, and third modulated light, respectively; a colored-light-combining optical system that combines the first, second, and third modulated light; a projection optical system that projects the combined light emitted from the colored-light-combining optical system; and a base frame that mounts a plurality of optical parts which are disposed in a light path extending from the illumination optical system to the projection optical system, at least one of the colored-light-separating optical system and the colored-light-combining optical system being provided with a prism which includes a selection film formed therein that selects light having a predetermined range of wavelengths, and the prism being bonded directly to the base frame.
