Abstract
Liquid crystal compositions are provided which have particularly a low threshold voltage, excellent miscibility at low temperatures, and a wide nematic phase range while satisfying several characteristics required of liquid crystal compositions for AM-LCD. The liquid crystal compositions contain, as a first component, at least one compound expressed by either formula (I-1) or (I-2), and as a second component, at least one compound expressed by any one of formulas (II-1) to (II-7) ##STR1## wherein n is an integer of 1 to 10, Z.sub.1 represents --CH.sub.2 CH.sub.2 -- or a single bond, X represents F, OCF.sub.3 or CF.sub.3, and Y represents H or F.
