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. 

Liquid crystal composition and liquid crystal display element

The present invention discloses a negative dielectric anisotropic liquid crystal composition, characterized in that the liquid crystal composition comprises one or more compounds represented by formula I, one or more compounds represented by formula II, one or more compounds represented by formula III and one or more compounds represented by formula IV, In the liquid crystal molecules of the composition, the van der Waals force therebetween is used as a motive force, such that the liquid crystal molecules generate an attractive force at an appropriate distance and positional relationships, thereby enabling the liquid crystal molecules to have excellent regular alignment characteristics, which is favorable for the liquid crystal molecules to modulate the transmission and blocking of light in the liquid crystal display device.
