Abstract
Liquid crystal cells containing mixtures of cholesteric optically active p-alkoxybenzylidene-p'-aminobenzonitrile compounds with nematic liquid crystal compounds form cholesteric liquid crystals which change to the nematic stage upon application of an electric field. Electro-optic devices including such liquid crystals have low voltage requirements and rapid response times.
