Abstract
An illumination system for a color display device includes means for separating the different polarizations of incoming light. One of the polarizations is rotated whereby the polarization of all the light directed toward the screen is the same. A lenticular lens array is used to focus light onto the cells of the picture elements. The three primary light colors are split so that the individual cells within the picture elements receive only the desired color of light.
