ABSTRACT:
Since a 1-(trifluoromethyl)naphthalene derivative of the present invention has negative dielectric anisotropy, has a very large absolute value, is chemically stable with heat, light, water, and the like, moreover, it excels in compatibility with a liquid crystal compound or a liquid crystal composition used widely nowadays, it is suitable as an element of a practical liquid crystal composition capable of low voltage drive. In addition, the liquid crystal composition using the compound of the present invention has low drive voltage, is useful as a constituent material of the liquid crystal display device of low consumption of electrical power, and can be used suitably for liquid crystal display devices such as a VA type and an IPS type, and the like.
