The invention discloses a liquid crystal composition which contains compounds shown in formulae I and II and also can contain one or more compounds shown in formula II-B, wherein the definitions of all substituents are given. The composition disclosed by the invention has low viscosity gamma 1, moderate dielectric anisotropy delta epsilon and moderate optical anisotropy delta n and can realize quick response of liquid crystal display.
Description
technical field [0001] The invention relates to the technical 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, ...
