    • A liquid crystal composition is realized, which composition simultaneously exhibits a negatively large .DELTA..di-elect cons. value suitable to .tau.-Vmin, and SA phase within a sufficient temperature range for realizing a good alignment. A smectic liquid crystal composition containing component (AI), component (B) and/or component (C), expressed by the following formulas: ##STR1## wherein R.sup.1 represents an alkyl group of 1 to 9 carbon atoms, R.sup.2 represents an alkyl group of 1 to 9 carbon atoms, R.sup.3 represents an alkyl group of 1 to 18 carbon atoms, R.sup.4 represents an alkyl group of 1 to 18 carbon atoms, X represents H or F, R.sup.5 represents an alkyl group of 6 to 15 carbon atoms and R.sup.6 represents an alkyl group of 6 to 15 carbon atoms. Ferroelectric liquid crystal material having a negative dielectric anisotropy is applicable to display element utilizing AC-stabilizing effect and .tau.-Vmin. Further, as to the composition containing ##STR2## as an additional component, SA phase appears within a broad range; hence the composition can be made up into a ferroelectric liquid crystal composition having a good alignment.
