Title:
液晶性化合物、液晶組成物および液晶表示素子
Document Type and Number:
Japanese Patent JP5458577
Kind Code:
B2
Abstract:
The invention provides a liquid crystal compound which has stability to heat, light and so forth, shows liquid crystal phases in a wide temperature range, and has a small viscosity, an appropriate optical anisotropy, a large dielectric anisotropy, and an excellent compatibility with other liquid crystal compounds. The invention provides a liquid crystal composition which has an appropriate optical anisotropy, an appropriate dielectric anisotropy, a low threshold voltage, and a high maximum temperature and a low minimum temperature of a nematic phase. The invention provides a liquid crystal display device which has a short response time, a small power consumption, a small driving voltage, and a large contrast, and can be used in a wide temperature range. The liquid crystal compound is a halogeno-benzene derivative having a trifluoropropenyl group or trifluoropropynyl group at a side chain, such as, for example, trans-4'-[3,5-difluoro-4-(3,3,3-trifluoropropenyl)phenyl]-trans-4-p ropylbicyclohexyl. The liquid crystal composition contains a compound which is this derivative. The liquid crystal display device uses this liquid crystal composition.
