ABSTRACT:
A liquid crystal composition comprising at least one first component compound of formula (I), at least one second component compound of formula (II) and at least one third component compound of formula (III), ##STR1## wherein R.sup.1 is alkyl of 1 to 8 carbons; R.sup.2 is H or F; R.sup.3 is alkyl or alkoxy each of 1 to 8 carbons; and R.sup.4 is F, --CN, alkyl or alkoxy each of 1 to 8 carbons, the first, second and third component compounds contained in respective amounts of 20-40 wt. %, 10-40 wt. % and 20-50 wt. % and in a total amount of 70 wt. % or more in the composition is provided to improve a steepness of transmission vs. voltage curve in a SBE mode display cell which is operated at a high level of multiplexing.
