摘要：
A ferroelectric chiral smectic liquid crystal composition, comprising at least one optically active compound represented by the following formula (I):
wherein R, denotes a linear or branched alkyl group having 1 - 18 cabon atoms capable of having a substituent; R 2 denotes a linear or branched alkyl group having 1 - 14 carbon atoms capable of having a substituent; and X 1 denotes a single bond, -0- or -
and at least one optically active compound represented by the following formula (II):
wherein R 3 denotes a linear alkyl group having 1 - 14 carbon atoms; R 4 denotes a linear or branched alkyl group having 1 - 14 carbon atoms capable of having a substituent; and X 2 denotes a single bond, -O- or
