LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY

摘要

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) <CHEM> <CHEM> wherein n is an integer of 1 to 10, Z1, represents -CH2CH2- or single bond, X represents F, OCF3, or CF3, 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.
