摘要:
A novel, superior, optically active liquid crystal compound exhibiting a smectic C* phase, and a liquid crystal composition containing the same are provided, which compound is expressed by the formula ##STR1## wherein X represents --CH.sub.2 O-- or --OCH.sub.2 --; Y represents --COO-- or --OCO--; and either one of R.sup.1 or R.sup.2 represents an optically active alkyl group, alkoxy group or alkoxycarbonyl group and the other represents a non-optically-active alkyl group or alkoxy group each of 4 to 18 carbon atoms.
