Abstract
To provide a highly reactive polymerizable compound having a high solubility in a liquid crystal compound; a liquid crystal composition satisfying at least one characteristic such as a high maximum temperature of a nematic phase, a low minimum temperature thereof, a small viscosity, a suitable optical anisotropy, a large negative dielectric anisotropy and specific resistance, a high stability to ultraviolet light and heat, and having a suitable balance regarding at least two characteristics; a PSA device having a short response time, a large pretilt angle, a small residual monomer concentration, a large voltage holding ratio and contrast ratio and a long life; a polymerizable compound into which one bonding group or nonidentical reaction group is introduced by constructing a polymer structure having a high polymerization degree in a PSA device manufacturing process to obtain a stable display, a liquid crystal composition containing thereof, and a liquid crystal device including thereof.
