摘要：
A novel liquid crystal compound represented by the general formula (I): ##STR1## (wherein R is a straight or branched alkyl or alkoxy group having 1 to 20 carbon atoms, R* is an optically active alkyl group having 4 to 20 carbon atoms, X is a fluorine atom or a chlorine atom, and n is 1 or 2), a liquid crystal composition containing at least one liquid crystal compound of the general formula (I), a chiral smectic liquid crystal composition containing at least one liquid crystal compound of the general formula (I), and an optical switching element utilizing the chiral smectic liquid crystal composition containing at least one liquid crystal compound of the general formula (I) are described.
