Ferroelectric chiral smectic liquid crystal composition and liquid crystal device using same.

摘要

A ferroelectric chiral smectic liquid crystal composition, comprising at least one optically active compound represented by the following formula (I): <CHEM> wherein R1 denotes a linear or branched alkyl group having 1 - 18 carbon atoms capable of having a subtituent; X1 denotes a single sbond, -O- or - @O-; Z denotes a single bond or - @O-; <CHEM> and n is an integer of 1 - 12; and at least one compound represented by the following formula (II): <CHEM> wherein R2 and R3 respectively denote a linear or branched optically inactive alkyl group having 1 - 18 carbon atoms capable of having an alkoxy group of 1 - 12 carbon atoms; X2 and X3 respectively denote a single bond, -O-, -O @-, -@O- or -O @O-; and p and q are respectively 0, 1 or 2 with proviso that both of p and q are not 0.
