Problems solved by technology

[0022] Although there are liquid crystal compositions with great negative dielectric anisotropy in the prior art, the characteristics of high steepness, low power consumption and fast response cannot be taken into account at the same time. For example, the compound proposed in CN108315017 has great The absolute value of negative dielectric anisotropy, but with the continuous advancement of technology, its steepness, response speed, power consumption and other aspects cannot fully meet the market demand

Abstract

The invention relates to a negative liquid crystal composition with a terminal alkene structure and application of the negative liquid crystal composition. The liquid crystal composition contains liquid crystal compounds shown as general formulas I, II, III, IV and V which are described in the specification. The negative liquid crystal composition has negative dielectric anisotropy, high gradient,especially low viscosity and short response time, has good stability and low-temperature intersolubility, strong UV resistance and high VHR and resistivity, and can be applied to display modes of VA,MVA, PVA, FFS, PSVA, IPS, TFT and the like.

Description

technical field [0001] The invention relates to a liquid crystal composition, in particular to a negative liquid crystal composition with terminal olefin structure. Background technique [0002] Liquid crystal display technology has been widely used in various sizes of displays in today's society. Small-sized displays such as calculators, mobile phones, meters, etc.; medium-sized displays such as computer monitors; large-sized displays such as TVs. Liquid crystal display has the advantages of high resolution, high brightness and flat panel display, light weight, low energy consumption and even flexible display. Therefore, LCD will continue to play an important role in the information technology era. [0003] The early liquid crystal display mode was TN display. People used the TN electro-optic effect and integrated circuits to make it into a liquid crystal display device (TN-LCD), which opened up broad prospects for the application of liquid crystals. TN-LCD has developed...
