PROBLEM TO BE SOLVED: To provide an optical component attaching structure capable of easily replacing optical components constituted of an optical modulator (liquid crystal panel) and a prism. SOLUTION: The optical components constituted of the liquid crystal panel 441B and the cross-dichroic prism 45 which are integrated into one body are fixed while hanging the components from the bottom side of an attaching member 447, and the attaching member 447 is freely attachably/detachably attached to the upper attaching part 473 of a lower light guide 471. Then, it is unnecessary to unscrew and insert a screw driver into the lower light guide 471 again in the case of replacing the optical components together with the attaching member 447. The trouble is eliminated that other optical components in the light guide are damaged by the driver, and the replacing work can be easily performed from upperward. |
