Abstract

The present invention relates to the technical field of liquid crystals, particularly to a liquid crystal composition containing a cyclohexenyl liquid crystal compound, wherein the liquid crystal composition contains one or a plurality of compounds represented by a general formula I and one or a plurality of compounds represented by a general formula II, the compound represented by the general formula I is a compound with a cyclohexene structure, and has high negative dielectric anisotropy, and the compound represented by the general formula II is a bicyclic structure compound, has low rotational viscosity, and can effectively reduce the rotational viscosity of the liquid crystal composition and improve the response time of the liquid crystal display device. According to the present invention, the liquid crystal composition has low rotational viscosity, can be used for quick-response liquid crystal display in various display modes, and can significantly improve the display effects of liquid crystal display devices in VA, MVA, PVA, PSVA and other VA mode display devices or IPS or FFS mode display devices. The formulas I and II are defined in the specification.

Description

technical field [0001] The invention relates to the field of liquid crystal technology, in particular to a liquid crystal composition containing a cyclohexenyl liquid crystal compound and its application. Specifically, the liquid crystal composition provided by the invention has negative dielectric anisotropy. Background technique [0002] At present, liquid crystals have been widely used in the field of information display, and at the same time, some progress has been made in the application in optical communication (S.T.Wu, D.K.Yang. Reflective Liquid Crystal DisplayY.Wiley, 2001). In recent years, the application fields of liquid crystal compounds have been significantly expanded to various display devices, electro-optic devices, electronic components, sensors, etc. Nematic liquid crystal compounds have been most widely used in flat panel displays, especially for TFT active matrix system. [0003] At present, negative liquid crystals are widely used in large-size TV liqu...
