Claim:
1. A projector comprising: a first light source apparatus; a second light source apparatus; a laser light source apparatus; a first light modulator that modulates light from the first light source apparatus to form first image light; a second light modulator that modulates light from the second light source apparatus to form second image light; a third light modulator that modulates light from the laser light source apparatus to form third image light, the light from the laser light source apparatus comprising laser light; a cross prism that combines the first image light, the second image light, and the third image light with one another; a projection system that projects light from the cross prism; and a secondary light source image formation system that forms a secondary light source image on an optical path between the laser light source apparatus and the third light modulator, wherein the secondary light source image is so shaped that the length thereof in a direction perpendicular to a central intersection line of the cross prism is longer than the length thereof in a direction parallel to the central intersection line.
