ABSTRACT:
A phase change liquid crystal device comprising a layer of liquid crystal material contained between two transparent slides which carry electrode structures for applying a voltage across the layer. The liquid crystal material is a mixture of nematic and cholesteric material having a smectic to cholesteric transition just below the operating temperature range of the device. This provides a cholesteric pitch change to compensate for changes with temperature in the elastic twist and dielectric constants.
