<P>PROBLEM TO BE SOLVED: To provide a projection display device for improving contrast of a projection image, in the projection display device which uses a reflection light valve. <P>SOLUTION: Light from a light source is color-separated into red light, green light and blue light, and then, they are made incident on a polarization splitter arranged at each color light. Each color light, incident on the polarization beam splitter, transmits a deflection separation part and is made incident on the reflection light valve. Each color light is modulated with the reflection type light valve; reflected and emitted light is made incident on the polarization beam splitter again, and reflected on the polarization separating part to be analyzed. Analyzed light after passing a polarizer is projected with a projection lens, after being color-composited. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
