Abstract
A multi-path reflective color liquid crystal display projection system utilizes one color separating dichroic mirror in combination with polarizing beam splitters and reflective liquid crystal displays to provide a high resolution, high brightness display. The dichroic mirror separates two color components (e.g., green and one of the red and blue components) and from the other (e.g., the other of the red and blue components). A color light separating polarizing beam splitter the receives the two selected color components of light and separates them from each other.
