摘要:
A dielectric negative liquid crystal composition, a liquid crystal display element and a liquid crystal display containing the liquid crystal composition belong to the field of liquid crystal display. The liquid crystal composition of the present disclosure includes a compound represented by formula I, a compound represented by formula II, two or more compounds represented by formula III and one or more compounds represented by formula IV. The liquid crystal composition of the present invention has high dielectric anisotropy, high elastic constant K, low rotational viscosity, can be used to develop large dielectric, fast response liquid crystal display elements or liquid crystal displays.
