A reflection-type laser projector ( 100 ) projects modulated laser beams outputted from a laser projection unit ( 40 ), on a screen, wherein a reflector ( 112 ) as a constituent of the screen ( 110 ) has reflection characteristics of reflecting, among the incident light, only laser beams of three colors of red, blue, and green, which are projected from the laser projection unit ( 40 ) and light in the neighboring wavelength band, and transmitting light in other wavelength bands, thereby preventing pictures on the screen ( 110 ) from becoming hard to be seen due to effects of indoor illumination or light from outdoors. |
