ABSTRACT:
A liquid crystalline compound which has a low viscosity and is electrically and chemically stable and compatible with other known liquid crystalline compounds at low temperatures, and a liquid crystal composition containing the same, which compound is a phenyl-4-cyclohexylbutylcyclohexane derivative expressed by the formula: ##STR1## wherein R represents a hydrogen atom or a linear or branched alkyl group of 1 to 15 carbon atoms, and X.sub.1, X.sub.2 and X.sub.3 are each independent and X.sub.1 and X.sub.3 each represent a hydrogen atom or a halogen atom and X.sub.2 represents a hydrogen atom or a linear or branched alkyl group of 1 to 15 carbon atoms (wherein one --CH.sub.2 CH.sub.2 -- bond may be replaced by a --CH.dbd.CH-- bond and one non-adjacent --CH.sub.2 -- bond may be replaced by an oxygen atom), a halogen atom, a cyano group, a trifluoromethyl group or a trifluoromethoxy group.
