Abstract
A transmissive active matrix liquid crystal display device has a multievel optical phase element that sepaeates each color component of light into a plurality of diffraction orders. The multilevel optical phase element is aligned with a an active matrix array and directs light of different colors through different pixels of a liquid crystal material. The transmission of light through the liquid crystal material is controlled by an array of transistor circuits that actuate pixel electrodes.
