Abstract
PURPOSE: A liquid crystals composition that is composed of a specific biphenyl, a phenylcyclohexane and a cyanophenyl cyclohexylbenzoate, thus keeping the nematic state over a wide temperature range including cryogenic temperature.
CONSTITUTION: (A) A biphenyl of formula I (R1 is 2W8C straight-chain alkyl, preferably ethyl-, n-propyl, n-butyl, straight-chain alkoxy, preferably ethoxy-n-propoxy-), (B) a phenylcyclohexane or formula II (R2 is 2W7C straight-chain alkyl, preferably ethyl), (C) cyanophenyl cyclohexylbenzoate of formula III (R3 is straight- chain alkyl of 2,4 or 5 carbon atoms) and (D) a biphenylcyclohexane of formula IV (R4 is straight-chain alkyl of 3W5 carbon atoms, preferably n-amyl) are mixed in amounts of 10W30wt% (A), 30W45wt% (B), 5W10wt% (C) and 10W30wt% (D) respectively to give the objective composition.
EFFECT: The response speed is high in the cryogenic zone.
