Abstract:
1. A projection-type display apparatus comprising; a laser source; an integrator which includes a plurality of rectangular lens cells arranged in a first direction and a second direction and is irradiated by laser light emitted from the laser source, the laser light incident on the integrator being a circular laser light, and the circular laser light being incident on one of the rectangular lens cells; a beam irradiation position moving unit configured to cause the laser light emitted from the laser light source to scan the surface of the integrator in the first and second directions, so that the circular laser light is sequentially projected onto every lens cell of the plurality of lens cells; a modulation device configured to modulate the laser light emitted from the integrator; and a projection lens configured to project the laser light modulated by the modulation device.
