Abstract
There is provided a liquid crystal composition having a sufficiently low viscosity (η), a sufficiently low rotational viscosity (γ1), a high elastic constant (K33), and a negative dielectric anisotropy (Δ∈), the absolute value of the negative dielectric anisotropy being large, without a reduction in the refractive index anisotropy (Δn) or the nematic phase-isotropic liquid phase transition temperature (Tni) thereof. By using the liquid crystal composition, it is possible to provide a liquid crystal display element, such as a VA-type liquid crystal display element, which eliminates or reduces the risk of a faulty display and realizes high display quality and a high-speed response. The liquid crystal display element including the liquid crystal composition according to the present invention may be suitably used as a liquid crystal display element for active-matrix driving and may also be used as, for example, a VA-type or PSVA-type liquid crystal display element.
