Abstract

A nematic liquid crystal composition suitable for use in displays and in other liquid crystal applications comprising a mixture of negative dielectric anisotropy low temperature characteristic nematic non-Schiff base liquid crystals and strongly positive dielectric anisotropy nematic non-Schiff base liquid crystals doped with traces of cholesteric liquid crystal are disclosed. These compositions have low actuation voltages and very rapid response times.
