[0003]However, the liquid crystal medium used in display elements such as VA mode is not perfect in itself. Compared with display elements with positive dielectric anisotropy, there is a dielectric Small size, slow response time, high driving voltage and other disadvantages, and it is more prone to poor display, afterimage and other problems

The invention relates to a liquid crystal composition, and a liquid crystal display element and a liquid crystal display comprising the liquid crystal composition, and belongs to the field of liquid crystal display. The liquid crystal composition comprises a compound represented by a formula I, a compound represented by a formula II, one or more compounds represented by a formula III, and at leastone polymerizable compound, wherein the formula I, the formula II and the formula III are described in the specification. The liquid crystal composition has characteristics of low rotational viscosity, high refractive index, and high response speed.
Description
technical field [0001] The present disclosure belongs to the field of liquid crystal display, and more specifically relates to a liquid crystal composition, a liquid crystal display element and a liquid crystal display containing the liquid crystal composition. Background technique [0002] The early commercial TFT-LCD products basically adopted the TN display mode, and the biggest problem was the narrow viewing angle. With the increase of product size, especially in the application of TV field, IPS display mode and VA display mode with wide viewing angle have been developed and applied in turn, especially based on the improvement of VA display mode, they have been successively introduced in major The company has achieved a breakthrough development, which is mainly due to the advantages of the VA mode itself, such as wide viewing angle, high contrast, and no need for rubbing alignment. In addition, the contrast displayed by the VA mode has a great influence on the optical an...
