Abstract
An antiferroelectric liquid crystal composition having a chiral smectic C,* phase composed by blending liquid crystal composition-constituting compounds having the same direction of inclination of optic axis produced by application of an electric field and/or comprised of a mixture of two enantiomers of a liquid crystal material; one having the stereosense (+) and the other having the stereosense (−). The stereosense is defined so that, when the molecule is viewed so that the bond between the core group and the asymmetric carbon is behind the asymmetric carbon atom, the stereosense is (+) if the remaining three groups (or atoms) are arranged clockwise in order of length of the groups (or, if the groups are the same length, in order of their volume), and the stereosense is (−) if the groups are arranged counter clockwise.
