Abstract: The present invention relates to a liquid crystal alignment agent, a liquid crystal device produced by using the liquid crystal alignment agent thereof, and a method for alignment of liquid crystal molecules by using the liquid crystal alignment agent. In more detail, the present embodiments relates to a novel liquid crystal alignment agent used in a method of aligning liquid crystal molecules, wherein the agent includes a molecule having a highly polar functional group grafted onto an end of the molecule.

Abstract: A liquid crystal diffractive light valve includes: a pair of opposed substrates wherein one of the substrates is a silicon wafer with associated electronics. The other substrate has an electrode layer facing the silicon substrate. And a ultraviolet curable composite material is disposed between the substrates which is then phase separated to form polymer walls having liquid crystal directors fixed therein regardless of application of an electric field across the electrode layers, and wherein pixel regions are formed between the polymer walls. The pixel regions have liquid crystal directors which are movable when an electric field is applied across the electrode layers. Application of an electric field allows for generation of phase differences between the wall and pixel regions to allow for Liquid Crystal on Silicon devices to be used as diffractive light valves.

Abstract: The present invention provides a full color liquid crystal display of passive matrix design that includes a polarizer, an analyzer having a transmission axis, and at least one light generation stage positioned between the polarizer and analyzer for transmitting light of a desired wavelength to the analyzer. This light generation stage includes a first retarder stack that rotates desired wavelengths of light to a particular polarization state, a second retarder stack inverted and rotated by 90 degrees with respect to said first retarder stack, and a passive matrix addressed optical element positioned between the first and second retarder stacks. The retardation and orientation of each of the first retarder stack, second retarder stack, and passive matrix addressed optical element are optimized so as to provide a color generation stage that places desired wavelengths of light substantially along the transmission axis of the analyzer.
