Abstract

The invention provides a liquid crystal mixture and an application thereof. The liquid crystal mixture comprises a liquid crystal compound with a general formula I and a liquid crystal compound with ageneral formula II, the general formula I is as shown in the specification, and the general formula II is as shown in the specification, wherein R is H or any one of alkyls provided with 1-7 carbon atoms; each of X1, X2, X3 and X4 is independently selected from H or F; Y is F, Cl, CF3, OCF3 or OCHF2; and each of the components marked by the letter A, B, C and D is independently selected from anyone of groups consisting of components as shown in the specifications. The liquid crystal mixture has a relatively high dielectric anisotropy value, a nematic phase with a relatively wide temperaturerange, a relatively high elasticity coefficient K and a high dielectric anisotropy value so as to be beneficial to the increment of contrast ratio and light transmittance of a liquid crystal display,the improvement of the quality of a display image and energy saving.

Description

technical field [0001] The invention relates to a liquid crystal mixture and its application, and belongs to the technical field of liquid crystal materials. Background technique [0002] Since entering the video era, liquid crystal displays have become ubiquitous from smartphones, tablet computers to smart TVs, and liquid crystal displays have become an indispensable "milk and bread" for the information society. The rapid development of liquid crystal display has replaced the traditional cathode ray tube display and has become the mainstream product in the field of information display, which directly affects the rapid development of liquid crystal materials, an important part of it. [0003] Liquid crystal media are partially ordered, anisotropic liquids that lie between three-dimensionally ordered solids and isotropic liquids. G.Friedel and F.Grand-jean of France made detailed research on the structure and optical properties of liquid crystals, and completed the work of l...
