Problems solved by technology

Small changes in liquid crystal molecules will cause obvious changes in the performance of conventional parameters of liquid crystals. Some of these changes have certain rules, and some seem to be difficult to find the rules. They will also have obvious effects on the interaction between liquid crystal molecules. These effects are very Subtle, so far there is no perfect theoretical explanation

Abstract

The invention discloses a liquid crystal composition. The liquid crystal composition comprises one or more types of compounds shown as formula I and one or more types of compounds shown as formula II; the liquid crystal composition comprises a compound shown as formula II-B in one or two types of compounds shown as the formula II of the description, wherein each substituent group is defined. The composition provided by the invention has low viscosity gamma1, moderate dielectric anisotropy deltaepsilon and moderate optical anisotropy deltan, and can realize rapid response of liquid crystal display.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal composition and a liquid crystal display element or a liquid crystal display containing the liquid crystal composition. Background technique [0002] At present, the application range of liquid crystal compounds is expanding more and more widely, and it can be applied to various types of displays, electro-optic devices, sensors, and the like. There are various types of liquid crystal compounds used in the above-mentioned display fields, among which nematic liquid crystals are most widely used. Nematic liquid crystals have been used in passive TN, STN matrix displays and systems with TFT active matrix. [0003] For the application field of thin film transistor technology (TFT-LCD), although the market has been huge in recent years and the technology has gradually matured, people's requirements for display technology are also constantly improving, especially ...
