Description

technical field

[0001] The invention relates to a liquid crystal composition, in particular to a liquid crystal composition with low rotational viscosity, large elastic constant and fast response time, and belongs to the field of liquid crystal materials and their applications. 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 (γ1 / K) of the liquid cr...
