A liquid crystal composition comprising 100 parts by mass of a nematic liquid crystal composition having negative dielectric anisotropy and 0.01 to 3 parts by mass of a polymerizable compound of general formula (I). On being irradiated with an energy ray, such as UV rays, the liquid crystal composition provides an LCD capable of high-speed response without undergoing reduction in reliability (voltage holding ratio).
In formula (I), rings C1, C2, and C3 are each benzene, cyclohexane or naphthalene; M1 and M2 are each hydrogen or methyl; Z1 is a direct bond, -L1-, -L1O-, etc.; Z4 is a direct bond, -L2-, -OL2-, etc.; at least one of Z1 and Z4 is not a direct bond; L1 and L2 are each C1-C10 alkylene; when Z1=Z4, one or more hydrogen atoms of the rings C1, C2, and C3 are substituted; Z2 and Z3 are each a direct bond, an ester bond, etc.; p and q are each 0 or 1, provided that p+q≥1.
一种液晶组合物,由 100 份(质量份)具有负介电各向异性的向列液晶组合物和 0.01 至 3 份(质量份)通式(I)的可聚合化合物组成。当受到能量射线(如紫外线)照射时,该液晶组合物可提供高速响应的液晶显示器,而不会降低可靠性(电压保持率)。
在式 (I) 中,环 C1、C2 和 C3 分别是苯、环己烷或萘;M1 和 M2 分别是氢或甲基;Z1 是直接键、-L1-、-L1O- 等;Z4 是直接键、-L2-、-OL2- 等。当 Z1=Z4 时,环 C1、C2 和 C3 的一个或多个氢原子被取代;Z2 和 Z3 各为直接键、酯键等;p 和 q 各为 0 或 1,条件是 p+q≥1。
