Abstract
Abstract A novel fluorophenylcyclohexane derivative useful as a component of liquid crystal compositions used for liquid crystal display elements, and a liquid crystal composition containing the same are provided, which fluorophenylcyclohexane derivative is expressed by the formula wherein R' represents an alkyl group of 1 to 10 carbon atoms; R 2 represents hydrogen atom, or an alkyl group or an alkoxy group each of 1 to 10 carbon atoms or a halogen atom of fluorine, chlorine or bromine or cyano group; either one of a' or a 2 represents fluorine atom and the other thereof represents hydrogen atom; A represents a 1,4-phenylene group or a laterally substituted 1,4-phenylene group wherein a substituent is selected from the group consisting of fluorine and chlorine atoms and a cyano group; ℓ and m each represent an integer of 0,1, 2 or 3; and a value of (ℓ + m) is between 1 and 3.
