Object of the present invention, the refractive index anisotropy (Δn) and a nematic phase - without lowering the isotropic liquid phase transition temperature (T ni), the solid phase-nematic phase transition temperature (T cn) is sufficiently low, the viscosity (η) is A liquid crystal composition having sufficiently small, a sufficiently low rotational viscosity (? 1), a large elastic constant (K 33 ) and a large absolute value and a negative dielectric anisotropy (??) is provided. The liquid crystal display device is excellent in display quality and has a high response speed. (N2) as the first component and at least one compound represented by the general formula (N3) as the second component and a compound having at least one compound having the dielectric anisotropy (? And at least one compound having an absolute value larger than 3, and to provide a liquid crystal display element using the liquid crystal composition. |
