摘要:
The subject is to provide a polymerizable compound having a suitable polymerization reactivity, a high conversion yield and a high solubility in a liquid crystal composition. The subject is to provide a liquid crystal composition having physical properties such as a high maximum temperature of a nematic phase, a low minimum temperature of a nematic phase, a small viscosity, a suitable optical anisotropy, a large dielectric anisotropy, a suitable elastic constant, a large specific resistance and a suitable pretilt. The subject is to provide a liquid crystal display device containing the composition and having a wide temperature range in which the device can be used, a short response time, a large voltage holding ratio, a low threshold voltage, a large contrast ratio and a long service life.
