ABSTRACT:
Liquid crystal compositions consisting essentially of certain N-(p-alkyloxybenzylidene)-p-alkylanilines with certain p-alkoxyphenyl-p'-alkylbenzoates and/or p-alkylphenyl-p'-cyanobenzoates exhibit a glassy structure at low temperatures, rather than a solid crystal form. The compositions also have a broad operating temperature range, suitable for use in liquid crystal displays. Liquid crystal displays incorporating these compositions maintain high contrast when exposed to low temperatures, while conventional liquid crystal compositions lose high contrast when so exposed to low temperatures.
