Abstract

The invention provides a liquid crystal composition. The composition comprises the following components: at least one compound with general formula I; at least one compound with general formula II andat least one compound with general formula III. The liquid crystal composition is provided with properly dielectric anisotropy, higher clearing point, higher optical anisotropy and good low temperature intersolubility, and other characteristics. Especially, the liquid crystal composition is provided with higher elastic constant. The invention also provides an application of the liquid crystal composition to liquid crystal displays, and the display has the advantages of fast response, high contrast, wide temperature width, and the like.

Description

technical field [0001] The invention relates to the field of liquid crystal display materials, in particular to a liquid crystal composition with suitable dielectric anisotropy, higher optical anisotropy, higher clearing point, good low-temperature miscibility and a faster response speed applications in liquid crystal displays. Background technique [0002] The classification of liquid crystal display elements 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 controlled birefringence (ECB), optically compensated bend (OCB), in-plane switching (IPS), vertical alignment (vertical alignment, VA), fringe field switching (fringe field switching, FFS), electric field sensing light Reactive alignment (field-induced photo-reactive alignment, FPA) and other modes. The classification of co...
