The invention relates to the field of a liquid crystal display material, in particular to a liquid crystal compound, a liquid crystal composition and application thereof. The liquid crystal compound has the following structure shown in the description. The invention also provides a preparation method of the compound and a liquid crystal composition containing the compound. A liquid crystal display device using the liquid crystal compound or the liquid crystal composition has low rotary viscosity, so that the response speed of the liquid crystal display device is accelerated; meanwhile, the characteristics of proper optical anisotropy values, high charge retention rate and the like are also achieved.
Description
technical field [0001] The invention relates to the field of liquid crystal display materials, in particular to a liquid crystal compound, composition and application thereof. Background technique [0002] The application of liquid crystal materials as environmental materials in the fields of information display materials and organic optoelectronic materials has great research value and bright application prospects. Liquid crystal materials have many advantages as new display materials, such as extremely low power consumption and low driving voltage. At the same time, compared with other materials, it also has the advantages of small size, light weight, long life, large amount of displayed information, and no electromagnetic radiation. It can almost meet the requirements of various information display, especially in TFT-LCD products. [0003] At present, the technology of TFT-LCD products has matured and successfully solved technical problems such as viewing angle, resoluti...
