Abstract

The invention discloses a liquid crystal composition, which comprises one or more compounds represented by a general formula II, one or more compounds represented by a general formula M, one or more compounds represented by a general formula A-1, and one or more compounds represented by a general formula A-2. The invention also discloses a display device containing the liquid crystal composition.The liquid crystal composition provided by the invention maintains the proper clearing point, and also has the advantages of large optical anisotropy, large dielectric anisotropy, low rotary viscosity, good low-temperature storage stability, large Kave value, large VHR (initial), large VHR (UV) and large VHR (high-temperature) (ie., good reliability), so that the liquid crystal display device containing the liquid crystal composition has small light scattering and high contrast, and is particularly suitable for a liquid crystal display element driven by an active matrix thin film transistor (AM-TFT).

Description

technical field [0001] The invention relates to the field of liquid crystal materials, in particular to a liquid crystal composition and a display device thereof. Background technique [0002] Liquid crystal display elements can be used in various home appliances represented by clocks and electronic calculators, measuring equipment, automotive panels, word processors, computers, printers, televisions, and the like. According to the type of display mode, it is divided into PC (phase change, phase change), TN (twist nematic, twisted nematic), STN (super twisted nematic, super twisted nematic), ECB (electrically controlled birefringence, electrically controlled birefringence), OCB (optically compensated bend, optically compensated bending), IPS (in-plane switching, coplanar transformation), VA (vertical alignment, vertical alignment) and other types. According to the driving method of the component, it is divided into PM (passive matrix, passive matrix) type and AM (active mat...
