Liquid crystal composition, liquid crystal oriented mixture and liquid crystal panel

Abstract

Disclosed are a liquid crystal composition, a liquid crystal alignment mixture (30) and a liquid crystal panel. The composition contains one or more difluoroalkenyl-substituted first liquid crystal molecules (33) and one or more second liquid crystal molecules (31) for vertical alignment. Through a stereoscopic effect caused by the first liquid crystal molecules (33) having difluoroalkenyl, the rate of occurrence of polymerization between a polymerizable monomer (32) and the first liquid crystal molecules (33) in a polymer alignment process can be effectively reduced, improving the occurrence of polymerization with polyimide on the surface of an alignment film (20), thereby solving the problem of image sticking.

Description

technical field [0001] The present invention relates to a liquid crystal composition, in particular to a liquid crystal composition composed of liquid crystal molecules with difluoroalkenyl groups, a liquid crystal alignment mixture and a liquid crystal panel. Background technique [0002] Liquid Crystal Display (LCD) is a flat-panel display device that uses the characteristics of liquid crystal materials to display images. Compared with other display devices, it has the advantages of thinness, low driving voltage, and low power consumption. Mainstream products in the consumer market. [0003] The main technical parameters for evaluating liquid crystal displays are: ①contrast ratio, ②brightness, ③response time and ④viewing angle. At present, the improvement of the response time of the liquid crystal display is mainly achieved through a liquid crystal panel containing a fast-response liquid crystal composition. [0004] Further, see figure 1 , figure 1 Shown is a schemati...

AI Technical Summary

Problems solved by technology

In order to achieve the effect of fast response, usually the liquid crystal mixture 30' will use liquid crystal molecules with double bonds, so the polymerizable monomer RM32' is more likely to bond with the liquid crystal molecules with double bonds during the alignment process, so that the obtained liquid crystal The panel has the problem of image sticking (Image Sticking)
