Nematic liquid-crystal compositions

摘要

Eutectic mixtures of nematic substances suitable for use as liquid crystals in electro-optic light valves which have a wide nematic range and which are preferably operative at or below normal room temperature are disclosed. A eutectic mixture containing p-methoxy-benzylidene-p'-n-butylaniline and p-ethoxy-benzylidene-p'-n-butylaniline is a preferred example.
