Zusammenfassung:	A light source, a color separator, a plurality of liquid crystal panels, a polarizing plate, a color synthesizing optical unit, and a projecting lens are disposed. The color synthesizing optical unit includes an x prism, a bonding base, a panel retaining member, and a panel installing member. The panel retaining member is fixed on the bonding base. The liquid crystal panels and the polarizing plate are installed on the panel installing member. The panel installing member can be separated from the panel retaining member. By this configuration, deviation of the convergence can be prevented with respect to the liquid crystal panels. Further, in practical use, it is easy to replace or repair the liquid crystal panel or the polarizing plate.
