Abstract

The invention provides a liquid crystal composition. The liquid crystal composition contains at least one compound of a formula I, at least one compound of a formula II, at least one compound of a formula III-1 and\or III-2, and at least one compound of a formula IV-1 and\or IV-2. The liquid crystal composition has high optical anisotropy, a high clearing point, appropriate dielectric anisotropy,and good low-temperature mutual solubility, and also has relatively large elastic constants K11 and K33. The invention also provides a liquid crystal display device containing the liquid crystal composition; and the liquid crystal display device has the advantages of fast response, high contrast, large temperature width range, and the like, thereby having a good display effect and a wide application range.

Description

technical field [0001] The invention relates to the field of liquid crystal display materials, in particular to a liquid crystal composition and a liquid crystal display device thereof. Background technique [0002] In liquid crystal display elements, the classification based on the operation mode of liquid crystal molecules is: phase change (phase change, PC), twisted nematic (twisted nematic, TN), super twisted nematic (super twisted nematic, STN), electrically controlled birefringence (electrically controlled birefringence, ECB), optically compensated bend (optically compensated bend, OCB), in-plane switching (IPS), vertical alignment (vertical alignment, VA), fringe field switching (fringe field switching, FFS), electric field Field-induced photo-reactive alignment (FPA) and other modes. The classification of component-based driving methods is: passive matrix (passive matrix, PM) and active matrix (active matrix, AM). PM is classified into static type (static), multipl...
