ABSTRACT:
A projection-type color display device. The display device includes a light source which provides light and a color separation member which receives the light and which separates the received light into the different colors of red, blue and green light. A light valve device receives the red, blue and green light and modulates the light to produce images. A color synthesis cube prism synthesizes the three monochromatic lights modulated by the light valve. A projection lens system projects the synthesized image onto a screen for viewing.
