摘要:
In a projection display apparatus, laser beams that are emitted from light sources and that are reflected and two-dimensionally scanned by scanning mirrors are modulated by a light bulb, and are then magnified through a projection lens to be projected. The F numbers of the scanning mirrors are smaller than that of the projection lens. The irradiation regions of the laser beams that are reflected by the scanning mirrors with respect to the light bulb are reduced by a lens.
