3,3'-DIFLUOROBIPHENYL DERIVATIVES, LIQUID CRYSTAL COMPOSITIONS, AND LIQUID CRYSTAL DISPLAY ELEMENTS

摘要

Liquid crystalline compounds which exhibit a negative dielectric anisotropy value, have an extremely high voltage holding ratio and a low threshold voltage, are small in their dependency on temperature, hardly exhibit smectic phase, and are excellent in miscibility with other liquid crystal materials at the same time; liquid crystal compositions comprising the compound; and liquid crystal display devices fabricated by using the liquid crystal composition are provided; the liquid crystalline compounds being specific 3,3'-difluorobiphenyl derivatives expressed by the following general formula (1):
