Abstract
PURPOSE: A N-type liquid crystal compound represented by a specific cyclohexane carbonic acid ester or its mixture is mixed with a P-type liquid crystal compound such as benzoic acid ester, thereby providing multidivision crystal which functions in a wide range of temperature with a small temperature dependence and a small Pth value.
CONSTITUTION: A liquid crystal having the above properties is provided. Such liquid crystal comprises a N-type liquid crystal compound represented by cyclohexane carbonic acid ester of the formula 1 (wherein R, R' is a C2-8 straight chain alkyl group), or admixuture thereof mixed with one or more of benzoic acid ester of the formula 2 or 3 (wherein R is a C2-7 straight chain alkyl group), diphenyl of the formula 4 (wherein R is a C5-8 straight chain alkyl group), or a cyclohexane carbonic acid ester of the formula 5 (wherein R is a C3-8 straight chain alkyl group).
