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.
