<P>PROBLEM TO BE SOLVED: To provide a rear projector and a projection system that can achieve high image quality by suppressing glaring of display through reliable and efficient prevention of scintillation. <P>SOLUTION: The rear projector includes: a screen 3; laser light sources 27R, 27G, and 27B; liquid crystal light valves 28R, 28G, and 28B that modulate the display light emitted from the laser light sources; an infrared laser light source 29 for excitation lights; liquid crystal light valves that modulate an excitation light emitted from the infrared laser light source; and a projection lens 25 that projects, onto the screen, the display light and the excitation light. The screen 3 includes a scattering plate configured by a chassis with a space therein and with at least one surface being light transmissive, and a scattering element filled in the space of the chassis with a light scattering material dispersed in a scattering medium, and the scattering element of the screen 3 is irradiated with the excitation light being the result of modulation. <P>COPYRIGHT: (C)2008,JPO&INPIT |
