Abstract

There is provided a liquid crystal composition having a dielectric anisotropy (Δε) large in absolute value, a sufficiently low viscosity (η), a sufficiently low rotational viscosity (γ), and a high elastic constant (K) without decreased refractive index anisotropy (Δn) or nematic phase-isotropic liquid phase transition temperature (T). A liquid crystal display device, such as a VA mode liquid crystal display device, including the liquid crystal composition has high response speed and good display quality with few or no display defects. The liquid crystal display device including the liquid crystal composition is useful as an active-matrix liquid crystal display device and is applicable as a liquid crystal display device such as a VA mode or PSVA mode liquid crystal display device.
