ABSTRACT:
A cross dichroic prism as a color-combining optical device and optical modulators constituting an optical device body are fixed with insulating pins being interposed. The optical device body includes a base and reinforcing members, supporting surfaces for supporting and fixing the reinforcing members are formed at a heat conductive member constituting the base. The reinforcing members are supported by the supporting surfaces of the heat conductive member, and also support and fix the optical modulators so as to enhance fixing state of the optical modulators relative to the cross dichroic prism.With this arrangement, an optical device as well as a projector, in which the connecting state of the optical modulators relative to the color-combining optical device can be strengthened so as to form a fine optical image without pixel deviation, can be provided.
