PROBLEM TO BE SOLVED: To provide a projector that changes display characteristics according to a use environment by having an optical device moving means. SOLUTION: A projector includes: first light modulation devices 60B, 60G, 60R that modulate illumination light; a second light modulation device 100 that further modulates the illumination light modulated by the first light modulation devices 60B, 60G, 60R; and a projection means 110 that projects the modulated illumination light toward a screen 120, and the optical device moving means 1 that moves an optical device 110 blocking at least part of the illumination light relatively to the light path of the illumination light to move the device off the light path in response to an external request.
