, (2008/06/13)
Liquid crystal materials for liquid crystal display, having a large negative dielectric anisotropy and maintaining a liquid crystal state at a broad temperature range including room temperature are provided. These materials contain novel compounds expressed by the general formula (I) STR1 wherein X represents STR2 Y represents STR3 R1 and R3 each represent an alkyl group or an alkyloxy group of 1-10 carbon atoms; R2 and R4 each represent an alkyl group of 1-10 carbon atoms; but compounds wherein STR4 are excluded.
