  There is provided a liquid crystal composition containing at least one compound represented by General Formula (a). There is also provided a liquid crystal display device using such a liquid crystal composition. The liquid crystal composition of the present invention has the following properties without suffering reductions in refractive index anisotropy (Δn) and nematic phase-isotropic liquid phase transition temperature (Tni): sufficiently low viscosity (η), sufficiently low rotational viscosity (γ1), a large elastic constant (K33), a high voltage holding ratio after UV exposure (VHR (UV)), and a negative dielectric anisotropy (Δε) with a large absolute value. A liquid crystal display device of, for example, a VA type that uses such a liquid crystal composition has a high response speed and excellent display quality with defective display being eliminated or reduced.
