Abstract

The invention discloses a liquid crystal composition and a liquid crystal display device. The liquid crystal composition contains at least one compound selected from a group composed of a formula I-1,a formula I-2 and a combination thereof, and at least one compound of a formula II. The liquid crystal composition provided by the invention has the advantages of good low-temperature mutual solubility, fast response, small LC light leakage, high contrast, and the like, and is particularly suitable for usage in 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 liquid crystal display device thereof. Background technique [0002] Liquid crystal display devices can be used in various home appliances represented by clocks and electronic calculators, measuring equipment, panels for automobiles, 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...
