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 negative Δ∈ with a high absolute value without decreasing the refractive index anisotropy (Δn) and the nematic phase-isotropic liquid phase transition temperature (Tni); and a liquid crystal display device with a VA mode or the like that uses the liquid crystal composition and has high display quality and high response speed. The liquid crystal display device that uses the liquid crystal composition of the present invention has a distinguished feature of high-speed response and is particularly useful as an active matrix driving liquid crystal display device. The liquid crystal display device is applicable to a VA mode, PSVA mode, PSA mode, IPS mode, or ECB mode liquid crystal display device.
