(57) [Abstract] (with correction) [Problem] To satisfy various characteristics required for AM-LCD, to have a low threshold voltage, to have a wide nematic temperature range, Provided is a liquid crystal composition having low viscosity, excellent in high-speed response, and capable of maintaining a high retention at a high temperature, and a liquid crystal display device using the same, or a liquid crystal composition / liquid crystal in which the above-mentioned disadvantages have been improved as compared with the related art. Provision of display elements. SOLUTION: General formula (1) A compound represented by the general formula (3) Wherein Y 1 is alkyl, alkoxy, F, CF 3 , CN, etc., and Y 3 is F or Cl, X 1 , X 2 , X 5 and X 6 are H or F. A nematic liquid crystal composition based on a mixture of polar compounds having a positive dielectric anisotropy. |
