Abstract
A projection-type display device includes a light source unit, an electro-optical device that modulates light emitted from the light source unit, and a projection optical system that projects the light modulated by the electro-optical device. In the electro-optical device, when a mirror that modulates light assumes an ON posture, the light from the light source unit is reflected in an ON direction toward the projection optical system and, when the mirror assumes an OFF posture, the light from the light source unit is reflected in an OFF direction different from the ON direction. An image capture element that receives incident light that has entered the projection-type display device from the outside via the projection optical system is provided in a direction in which the incident light is reflected by the mirror that assumes the OFF posture.
