Abstract
Liquid crystal compositions are provided which have a particularly excellent miscibility at low temperatures, properly large .DELTA.n, and small Vth and viscosity while satisfying several characteristics required of liquid crystal composition for AM-LCD. Disclosed are liquid crystal compositions containing, as a first component, at least one compound expressed by general formula either (I-1) or (I-2), and containing, as a second component, at least one compound expressed by any one of general formulas (II-1) to (II-7) ##STR1## wherein n is an integer of 1 to 10, Z.sup.1 represents --CH.sub.2 CH.sub.2 -- or single bond, X represents F or OCF.sub.3, Y represents H or F, and m is 0 or 1. The liquid crystal compositions of the present invention are useful as liquid crystal material for low voltage in several modes such as active matrix mode and STN mode.
