Abstract
A liquid crystal projector using monochromatic liquid crystal displays (LCDs). The liquid crystal projector includes a filter for filtering light emitted from a light source and for outputting a white light. A condenser lens group then condenses the white light, and, thereafter, the condensed white light is separated into the three primary colors of light by (color filters and applied to an LCD part comprising monochromatic LCDs. The LCD part outputs video images corresponding to the three primary colors of light separated according to an applied video signal. A reflective part their combines the outputted video images and outputs the combined video image to a projector lens. Finally, the projector lens projects the combined video image onto a screen.
