摘要：
The present invention provides a projection display system, comprising: plural laser light sources; an illumination optical system for illuminating, in different beam axes, light beams emitted from the individual laser light sources; a deflection mirror device, constituted by plural mirror elements, for modulating the light beams illuminated by the illumination optical system; and a projection optical system for projecting a reflection light from the deflection mirror device illuminated by the light beams.
