ABSTRACT:
A ferroelectric liquid crystal composition, comprising at least three mesomorphic compounds represented by the following formula (I): ##STR1## wherein C* denotes an asymmetric carbon atom; E denotes a mesomorphic compound residue including a divalent 6-membered ring-containing group capable of having a substituent; and A and B are mutually different groups respectively selected from the class of (a) methyl group, (b) linear or branched alkyl groups having 2-18 carbon atoms capable of having a substituent, (c) linear or branched alkyloxy groups having 1-18 carbon atoms, (d) linear or branched alkyloxyalkyl groups having 2-18 carbon atoms, (e) linear or branched alkyloxycarbonyl groups having 2-18 carbon atoms, (f) linear or branched alkyloxycarbonylmethyl groups having 3-18 carbon atoms; (g) chlorine or bromine, (h) fluorine, (i) trifluoromethyl group, and (j) cyano group; the above-mentioned at least three mesomorphic compounds belonging to at least three mutually different series of compounds which are different from each other in the combination of the groups A and B attached to the asymmetric carbon atom respectively selected from any one of the sub-classes (a)-(j).
