A liquid crystalline compound represented by formula ##STR1## wherein R denotes an alkyl or alkoxy group having 1 to 20 carbon atoms,

Liquid crystalline compounds having substituents

An optically active carboxylic acid derivative represented by the general formula ##STR1## wherein R represents a normal alkyl group having 1 to 20 carbon atoms, m and n represent 0 or 1 but are not 1 at the same time, X represents a hydrogen or halogen atom, Y represents a hydrogen or fluorine atom, provided that when Y is a hydrogen atom, X is a halogen atom, and that when n is 0, Y is ahydrogen atom, and Q* represents an optically active alkyl or 1-alkoxyethyl group having an asymmetric carbon atom.
