Abstract
Description
technical field
[0001] The invention belongs to the field of liquid crystal compounds and their applications, and relates to a novel cyclopentylethylene compound with negative dielectric anisotropy and its preparation method and application, and also relates to a liquid crystal medium containing the compound, which is suitable for passive or Active drive liquid crystal display technology. Background technique
[0002] At present, TFT-LCD has been widely used in industrial fields and household consumption fields, almost completely replacing the traditional CRT display market. According to different liquid crystal display methods, liquid crystal display elements can be divided into twisted nematic (TN) mode, super twisted nematic (STN) mode, in-plane (IPS) mode, vertical alignment (VA) mode and other modes.
[0003] Most of the current liquid crystal display elements are twisted nematic (TN) mode, but it has the disadvantages of low contrast and narrow viewing angle, while th...
