摘要: The present invention provides a liquid crystal composition formed by combining a polymerizable compound represented by formula I with a specific liquid crystal component, particularly a PSVA liquid crystal composition for displays or TV applications and a PSA-IPS liquid crystal composition for an IPS mode, and a liquid crystal display element or liquid crystal display comprising this liquid crystal composition; in particular, the polymerizable compound has a faster polymerization rate, and a “material system” formed from the selected polymerizable component and liquid crystal component should have the lowest rotary viscosity and the best photoelectric properties, and has a high VHR after (UV) photoradiation, this avoiding the problem of the occurrence of residual images to final displays.

摘要: There is provided a liquid crystal composition having the following properties without suffering reductions in refractive index anisotropy (Δn) and nematic phase-isotropic liquid phase transition temperature (Tm): sufficiently low viscosity (η), sufficiently low rotational viscosity (γ1), a large elastic constant (K33), and a negative dielectric anisotropy (Δ∈) with a large absolute value. There is also provided a liquid crystal display device of, for example, a VA type that uses such a liquid crystal composition and that has a high response speed and excellent display quality with defective display being eliminated or reduced. In particular, a liquid crystal composition having a negative dielectric anisotropy is provided, the composition containing a first component that is at least one compound represented by General Formula (i) and a second component that is at least one compound selected from compounds represented by General Formula (L).
