摘要：
A novel chiral liquid crystal compound having an optically active group which affords a superior response rate when used as a liquid crystal display element, and a liquid crystal composition containing the same are provided, which chiral liquid crystal compound is expressed by the formula ##STR1## wherein R represents an alkyl group of 1 to 18 carbon atoms; R* represents an optically active alkyl group of 4 to 15 carbon atoms; X represents single bond, --O--, ##STR2## Y represents --CH.sub.2 O-- or --OCH.sub.2 --; Z represents single bond, --O--, ##STR3## and m and n each represent 1 or 2.
