Abstract

The invention relates to a high-gradient quick-response negative dielectric anisotropy liquid crystal composition and application thereof. The liquid crystal composition contains liquid crystal compounds shown as general formulas I, II, III, IV and V. The liquid crystal composition has an extremely large absolute value of negative dielectric anisotropy and also has high gradient, low viscosity andshort response time, and meanwhile, the liquid crystal composition has better stability and low-temperature intersolubility, stronger anti-UV (Ultraviolet) capability and high VHR (Very High Ratio) and resistivity, and can be applied to display modes such as VA (Vertical Alignment), MVA (Multi-Vertical Alignment), PVA (Polyvinyl Alcohol), FFS (Fringe Field Switching), PSVA, IPS (In-Plane Switching) and TFT (Thin Film Transistor).

Description

technical field

[0001] The invention relates to a high-steep and fast-response negative dielectric anisotropy liquid crystal composition 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. Small-sized displays such as calculators, mobile phones, meters, etc.; medium-sized displays such as computer monitors; large-sized displays such as TVs. 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] The early liquid crystal display mode was TN display. People used the TN electro-optic effect and integrated circuits to make it into a liquid crystal display device (TN-LCD), which opened up broad prospects...
