A liquid crystal composition having one or more compounds shown as formula I and one or more compounds shown as formula II, and the liquid crystal composition comprising a compound shown as formula II-A: n n n n n n n n n n n n wherein substituents are all defined. The composition has a low viscosity γ 1 , a moderate dielectric anisotropy Δε and a moderate optical anisotropy Δn, and can achieve fast response of a liquid crystal display. |
