A projector includes a first light source, a first light modulator on which first light is incident, a first polarization separator disposed on a first optical path along which the first light emitted from the first light source and entering the first light modulator travels, a first retardation film disposed on the first optical path, a first reflector disposed on the first optical path, and a second light modulator on which second light different from the first light is incident. The first optical path passes through the first polarization separator and the first retardation film, is then deflected back by the first reflector, and reaches the first light modulator via the first retardation film and the first polarization separator. A second optical path along which the second light travels is independent of the first optical path and does not intersect the first optical path.
