Abstract

The invention relates to a negative liquid crystal composition with excellent low-temperature storage and display performance and an application thereof. The liquid crystal composition comprises liquid crystal compounds represented by general formulas I, II, III, IV and V. The liquid crystal composition has quite good low-temperature intersolubility and low-temperature response speed while havinga quite large absolute value of negative dielectric anisotropy; meanwhile, the liquid crystal composition has good stability, low viscosity, strong UV resistance, high VHR and high resistivity, and can be applied to VA, MVA, PVA, FFS, PSVA, IPS, TFT and other display modes.

Description

technical field [0001] The invention relates to a negative liquid crystal composition with excellent low-temperature storage and display performance and an application thereof, belonging to the technical field of liquid crystal materials. Background technique [0002] Liquid crystal display technology has been widely used in various sizes of displays in today's society. Liquid crystal display has the advantages of high resolution, high brightness and flat panel display, light weight, low energy consumption and even flexible display. Therefore, LCD will continue to play an important role in the information technology era. [0003] Currently, there are various display modes on the market, and the more competitive display modes mainly include in-plane switching (IPS), fringe field switching (FFS) and vertical alignment (VA). Among these display modes, in-plane switching (IPS) and fringe field switching (FFS) are characterized by wide viewing angles. When the negative liquid ...
