The present invention provides one or more kinds of the general formula (a) A liquid crystal composition of the compound represented and a liquid crystal display element using the same. The liquid crystal composition of the present invention does not reduce the refractive index anisotropy (Δn) and the nematic phase-isotropic liquid phase transition temperature (T ni ), the viscosity (η) is small enough, and the rotational viscosity (γ 1 ) is small enough. The elastic constant (K 33 ) is large, the voltage holding ratio (VHR(UV)) after UV irradiation is high, and the negative dielectric anisotropy (Δε) having a large absolute value is obtained, and thus the use thereof can be obtained. The VA type or the like does not have a liquid crystal display element which is excellent in display quality and has a fast response speed in which display failure or display failure is suppressed. |
