Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a nematic liquid crystal composition containing 2-methyl-3,4,5-trifluorobenzene liquid crystal compound and non-polar bicyclic compound and its application in fast-response TN / Application in IPS / FFS type TFT liquid crystal display. 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...
