Abstract:
Provided is a projector that makes it possible to use an optical system in common between different types of device. This projector (1) is provided with an optical unit (4) that forms an image, and a projection optical device (5) that projects the formed image. The optical unit (4) is provided with: a first lighting device (41); a first light modulation device (461R) that modulates light emitted from the first lighting device (41); and a dimming device (45R) that is disposed on an optical path between the first lighting device (41) and the first light modulation device (461R) and adjusts, for each region, the illuminance of the light emitted from the first lighting device (41). The dimming device (45R) has a reflective second light modulation device (452) that modulates the light emitted from the first lighting device (41), and a reflective relay device (453) that forms the modulated light modulated by the second light modulation device (452) into an image in the first light modulation device (461R).
