Abstract
Two light modulators, a first light modulator and a second light modulator, suffice for four light sources, a first light source, a second light source, a third light source, and a fourth light source, whereby the cost can be lowered as compared with a configuration in which three light modulators are required. As a result, cost reduction is achieved. Further, since two light modulators suffice, the size of the projector can be reduced as compared with the configuration in which three light modulators are required.
