An optically active lactone derivative represented by the following general formula (I):
wherein R¹ represents a straight-chain or branched alkyl, alkoxyl, alkanoyloxy, alkoxycarbonyl, alkoxyalkyl, alkoxyalkanoyloxy, or alkoxyalkoxyl group having 1 to 20 carbon atoms or an optically active group of each of the above kinds, R² represents a straight-chain or branched alkyl group having 1 to 20 carbon atoms,
and the asymmetric carbon atoms at the 2- and 4-positions in the lactone ring each independently is of the (S) or (R) configuration, an intermediate therefor, a process for producing the intermediate, a liquid-crystal composition, and a liquid-crystal display device.
