Abstract

The invention relates to the liquid crystal field, and especially relates to a liquid crystal composition and applications thereof in the liquid crystal display field. The liquid crystal composition is composed of the following compounds in parts by weight: 5 to 40 parts of one or more compounds represented by the formula I, 2 to 30 parts of one or more compounds represented by the formula II, and 20 to 70 parts of one or more compounds represented by the formula III, and may also comprises 4 to 30 parts of one or more compounds represented by the formula IV, or / and 5 to 25 parts of one or more compounds represented by the formula V to IX. By the cooperation among the compounds, the rotation viscosity of the liquid crystal composition can be effectively reduced, the related performances of mixed liquid crystal are improved, and thus the responding time is reduced. The provided liquid crystal composition can be used to produce quick response liquid crystal display with a plurality of display modes.

Description

technical field [0001] The invention relates to the field of liquid crystals, in particular to a liquid crystal composition and its application in the field of liquid crystal displays. 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 of optical communication. 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, especially since the 1970s, due to the development of large-scale integrated circuits and liquid crystal materials, the application of liquid crystal in display has ac...
