The present invention, the refractive index anisotropy (Δn) and a nematic phase - without lowering the isotropic liquid phase transition temperature (T ni), was sufficiently small, the viscosity (η), rotational viscosity (γ1) is small, the spring constant (K 33) sufficiently And has a negative absolute value of large DELTA epsilon, and further provides a liquid crystal display element having excellent display quality such as a VA type using such a liquid crystal composition and a high response speed. The liquid crystal display device using the liquid crystal composition of the present invention has a remarkable feature of high speed response and is particularly useful for a liquid crystal display device for active matrix drive and is suitable for a VA mode, a PSVA mode, a PSA mode, an IPS mode or an ECB mode Can be applied. |
