Abstract

The present invention relates to a fast response liquid crystal composition, which comprises at least one or a plurality of compounds represented by a general formula I, one or a plurality of compounds represented by a general formula II, and one or a plurality of compounds represented by a general formula III. According to the present invention, the liquid crystal composition has advantages of low rotation viscosity, large elastic constant, good low-temperature mutual solubility and fast response speed, can be used for fast response liquid crystal display of various display modes, can significantly improve the display effects of liquid crystal display devices in TN, IPS or FFS mode display devices, and is especially suitable for IPS and FFS mode liquid crystal display devices. The formulas I, II and III are defined in the specification.

Description

technical field [0001] The invention relates to a liquid crystal material and its application field. The liquid crystal material provided by the invention is a nematic phase liquid crystal composition. 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 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. Nematic liquid crystal compounds have been most widely used in flat panel displays, especially for TFT active matrix system. [0003] Liquid crystal display has experienced a long development path with the discovery of liquid crystal. In 1888, the Austrian botanist Friedrich Reinitzer discovered the first liquid cr...
