Problems solved by technology

When achieving high-speed response, it is often difficult to achieve a high penetration rate, because while increasing the penetration rate, it will cause an increase in rotational viscosity, thereby reducing the response speed

Abstract

A liquid crystal composition contains one or more compounds represented by formula I, one or more compounds represented by formula II, and one or more compounds represented by formula III. The liquidcrystal composition has a low viscosity, can realize quick response, and has a moderate dielectric anisotropy delta epsilon, a proper optical anisotropy delta n and a high stability to heat and light.A liquid crystal display element or a liquid crystal display containing the liquid crystal composition has the advantages of wide nematic phase temperature range, proper birefringence anisotropy, very high resistivity, good ultraviolet resistance, high charge retention rate, low vapor pressure and the like.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal composition, and a liquid crystal display element or a liquid crystal display containing the liquid crystal composition. Background technique [0002] In the development process of LCD, the liquid crystal used in LCD is developing toward the direction of faster response speed and better reliability, and the high-speed response characteristic of liquid crystal mixture comes from the corresponding physical parameters of its components, such as rotational viscosity γ1, elastic constant ( K), etc., high Δn helps to reduce the thickness of the liquid crystal cell, thereby improving the response speed, and at the same time, the high clearing point is also helpful for the combination and matching of mixed crystals. It can be seen from this that an ideal liquid crystal monomer should have the characteristics of low γ1, appropriate refractive index, and hig...
