Abstract
The invention discloses a liquid crystal composition and a liquid crystal display device. The liquid crystal composition contains at least one compound of a formula I, and at least one compound of a formula II. The liquid crystal composition provided by the invention also has good low temperature mutual solubility while maintaining suitable optical anisotropy, a high clearing point and a large absolute value of dielectric anisotropy. When the liquid crystal composition is applied to the liquid crystal display device, the liquid crystal display device can exhibit the advantages of good weatherresistance, high contrast, and the like.
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...
