Beschreibung
Zusammenfassung:	A projector includes a first light source apparatus, a second light source apparatus, a laser light source apparatus, a first light modulator, a second light modulator, a third light modulator that modulates light from the laser light source apparatus, a cross prism that combines first image light, second image light, and third image light formed by the respective light modulators with one another, 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, and 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.
