Abstract
Abstract Novel ferroelectric liquid crystalline compounds having a superior stability and chiral, smectic liquid crystalline compositions containing at least one kind of the same are provided, which compounds are expressed by the general formula wherein represents 1,4-phenylene group or 1,4-trans-cyclohexane group an optically active alkyl group; m = 0, 1 or 2; n = 1 or 2; X, a linear chain or brached alkyl group or alkoxy group, each having 1 to 18 carbon atoms; and when presents m = 1; and n = 1, X represents a linear chain or branched alkyl group having 1 to 18 carbon atoms or a linear chain alkoxy group having 11 to 18 carbon atoms.
