ABSTRACT:
A liquid crystal display device is described which includes two transparent sheets separated by a given distance, with liquid crystal material being disposed therebetween. Adjacent one transparent sheet is a stack of at least three pleochroic polarizers which act to separately polarize each incoming primary color wavelength. A second stack of at least three pleochroic polarizers are adjacent the second transparent sheet and are oriented to select the primary color polarizations exiting from the liquid crystal structure.
