The invention relates to a liquid crystal material and application fields thereof, particularly to a liquid crystal composition containing a fluoroterphenyl structure compound and a 2-methyl-3,4,5-trifluorobenzene structure compound, and applications thereof. According to the present invention, the liquid crystal composition comprises compounds represented by general formulas I, II and III, has characteristics of low rotational viscosity, high electrical resistivity, suitable optical anisotropy, good low-temperature mutual solubility, high elastic constant, excellent light stability and excellent thermal stability, and can reduce the response time of liquid crystal display devices so as to solve the problem of slow response of liquid crystal display devices, such that the liquid crystal composition is suitable for fast response TN, IPS and FFS type TFT liquid crystal display devices, particularly for IPS and FFS liquid crystal display devices. The general formulas I, II and III are defined in the specification.
Description
technical field [0001] The invention relates to the field of liquid crystal material and its application, in particular to a liquid crystal composition containing a fluorinated terphenyl compound and its application. 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 ...
