The invention particularly relates a fast-response liquid crystal composition, belonging to the field of liquid crystal displays. The fast-response liquid crystal composition comprises more than 40% by mass of a compound as shown in a formula I which is described in the specification and at least one compound represented by a general formula II as described in the specification, wherein the compound represented by the general formula II is a polar compound containing a 2-methyl-3,4,5-trifluorobenzene structure and a difluoromethoxy bridged bond, and the structure has large dielectric anisotropy. The liquid crystal composition of the invention has low viscosity, high electrical resistivity, good low-temperature mutual solubility and a fast response speed and can be used for fast-response liquid crystal displays of various display modes; when applied to displays of TN, IPS or FFS modes, the liquid crystal composition can obviously improve the display effect of the displays; and the liquid crystal composition is especially applicable to liquid crystal displays of IPS / FFS modes.
Description
technical field [0001] The present invention relates to the field of liquid crystal materials, in particular to a liquid crystal composition with low rotational viscosity and large optical anisotropy. field applications. Background technique [0002] At present, liquid crystals are 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 Displays. 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. For this reason, many different structures have been proposed, especially in the field of nematic liquid crystals, and nematic liquid crystal compounds have been most widely used in flat panel displays so far. Especially for TFT active matrix systems. [0003] Liquid crystal display has experienced a ...
