ABSTRACT:
A chiral nematic liquid crystal-polymer composite capable of having a paper-white off-state and a highly transparent on-state. The composite includes droplets of at least two different liquid crystal materials. The different liquid crystal materials are isolated from each other and have different reflection bands. The composite is suitable for use in light valves generally and direct view and projection displays particularly.
