摘要： The present invention provides a technology for mounting a prism which is used for a projector, such as a crossed dichroic prism, accurately in a predetermined position of a base frame. A projector for displaying color images can include an illumination optical system, a colored-light-separating optical system for separating light emitted from the illumination optical system into first, second, and third colored light which are three color components, 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. The projector can further include a colored-light-combining optical system for combining the first, second, and third modulated light, a projection optical system for projecting the combined light emitted from the colored-light-combining optical system, and a base frame for mounting a plurality of optical parts which are disposed in a light path between the illumination optical system and the projection optical system. The colored-light-combining optical system can be a crossed dichroic prism bonded directly to the base frame.
