Abstract
A liquid crystal composition, a liquid crystal display element and a liquid crystal display comprising the liquid crystal composition belong to the field of liquid crystal display. The liquid crystal composition comprises a compound represented by formula I with a mass content of 1-10% as the first component, a compound represented by formula II with a mass content of 1-20% as the second component, more than two compounds represented by formula III as the third component, more than three compounds represented by formula IV as the fourth component, and one or more polymerizable compounds as the fifth component, the crystal composition has low rotational viscosity and low γ1/K33 on the basis of maintaining appropriate optical anisotropy. When applied to liquid crystal display elements or liquid crystal displays, the liquid crystal display has a fast response speed.
