An object of the present invention is to provide liquid crystalline compounds and liquid crystalline compositions suitable for liquid crystalline materials such as IPS mode in which negative dielectric anisotropy being required.
A liquid crystalline compound expressed by the general formula (1)
whrein, R1 and R2 being alkyl group having from 1 to 10 C atom(s) etc., Z1 to Z4 being -(CH2)2- etc., A1 to A3 being 1,4-cyclohexylene etc., Q1 and Q2 being -CH2- etc., X being optionally haloalkyl or -CH2-, k, l, m and n being 0 or 1, provided that l+k+m+n≦3, each independently.
本发明的目的是提供适用于需要负介电各向异性的 IPS 模式等液晶材料的液晶化合物和液晶组合物。
由通式(1)表示的液晶化合物
其中,R1 和 R2 为具有 1 至 10 个 C 原子的烷基等,Z1 至 Z4 为-(
CH2)2-等,A1 至 A3 为 1,4-
环己烯等,Q1 和 Q2 为- -等,X 可选为卤代烷基或- -,k、l、m 和 n 为 0 或 1,条件是 l+k+m+n ≦3,且各自独立。
