Abstract
Provided are a polymerizable compound represented by formula I and a liquid crystal composition formed by combining such a polymerizable compound 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; in particular, the polymerizable compound has a faster polymerization rate, and a “material system” formed from the selected polymerizable component and liquid crystal component has a low rotary viscosity and good photoelectric properties, and has a high VHR after (UV) photoradiation, this avoiding the problem of the occurrence of residual images to final displays.
