Abstract
PURPOSE: To provide a liquid crystal compsn. for a positive type guest-host, which lowers Vsat without losing a low-temperature response and has sufficient response at a low voltage, by a method wherein a specified cpd. is added to a conventional nematic liquid crystal.
CONSTITUTION: A cpd. of the formula (wherein R, R' are 1W8C straight-chain alkyl; X is halogen, cyano) and, if necessary, a dichromatic coloring mater (in which absorption coefficient with respect to light parallel with the molecular axis of the coloring matter molecule is different from that with respect to light perpendicular to the molecular axis of the coloring matter molecule), an optically active agent (having a concentration of p<d wherein p is a helical pitch and d is a thickness of cell), or a cholesteric liquid crystal are added to a conventional nematic liquid crystal to obtain a liquid crystal compsn. which has sufficient response at 6 volts.
