Abstract:
Provided is a polymerizable compound with large solubility in a liquid crystal composition and high reactivity irradiated by ultraviolet in the longer wavelength range. Provided is a liquid crystal composition that satisfies at least one of characteristics such as high maximum temperature of a nematic phase, low minimum temperature of a nematic phase, small viscosity, suitable optical anisotropy, large negative dielectric anisotropy, large specific resistance, high stability to ultraviolet light and high stability to heat, or that is suitably balanced between at least two of the characteristics. Provided is the polymerizable compound wherein at least one of a 1,3-phenylene structure and a 2,7-fluorenediyl structure is introduced to the polymerizable compound to give stable displays by forming a polymer with a high degree of polymerization in a PSA device production process using longer wavelengths, the liquid crystal composition includes the compound, and the liquid crystal display device contains the composition.
