Liquid crystal compositions are provided which have particularly a low threshold voltage, excellent miscibility at low temperatures, and wide nematic phase range 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)

wherein n is an integer of 1 to 10, Z 1 , represents -CH 2 CH 2 - or single bond, X represents F, OCF 3 , or CF 3 , and Y represents H or F.
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.
