Abstract

The invention relates to a liquid crystal material and an application field thereof, particularly to a liquid crystal composition containing fluoro terphenyl, and applications thereof, wherein the liquid crystal composition comprises compounds represented by formulas I, II and III. According to the present invention, the liquid crystal composition has characteristics of low rotational viscosity, large elastic constant, good low-temperature mutual solubility and fast response speed, can be used for fast response liquid crystal display with various display modes, can significantly improve the display effects of liquid crystal display devices in TN, IPS or FFS mode display devices, and is especially suitable for IPS and FFS mode liquid crystal display devices. The general formulas I, II and III are defined in the specification.

Description

technical field [0001] The invention relates to the field of liquid crystal material and its application, in particular to a liquid crystal composition containing fluorinated terphenyl and its application. Background technique [0002] At present, LCD product technology has matured, successfully solved technical problems such as viewing angle, resolution, color saturation and brightness, and its display performance has approached or exceeded that of CRT displays. Large-size and small and medium-sized LCDs have gradually occupied the mainstream position of flat panel displays in their respective fields. However, limited by the liquid crystal material itself (high viscosity), the response time becomes the main factor affecting high-performance displays. [0003] Specifically, the response time of the liquid crystal is limited by the rotational viscosity γ1 and the elastic constant of the liquid crystal, and reducing the rotational viscosity and increasing the elastic constant...
