Abstract

The invention provides a liquid crystal composition containing polymerizable compounds and a liquid crystal display device. The liquid crystal composition comprises at least one polymerizable compound shown as a general formula I, at least one compound shown as a general formula II and at least one compound shown as a general formula III. The liquid crystal composition has relatively long low-temperature storage time, relatively good pre-tilt angle stability and relatively low polymer residue under the conditions of relatively small polymer layer surface roughness and relatively high VHR, and can effectively improve the problem of broken bright spots existing in a liquid crystal display when being applied to the liquid crystal display, so that the liquid crystal display has relatively good application prospects. The liquid crystal display device has the advantages of improving the display quality of the liquid crystal display device, accelerating the production process of the PSA type liquid crystal display device, accelerating the production efficiency, improving the problems of'image sticking 'and uneven display in the liquid crystal display device, and having higher practical application value.

Description

technical field [0001] The invention relates to the field of liquid crystals, in particular to a liquid crystal composition containing a polymerizable compound and a liquid crystal display device containing the liquid crystal composition. Background technique [0002] Liquid Crystal Display (LCD) has achieved rapid development due to its small size, light weight, low power consumption and excellent display quality, and is especially widely used in portable electronic information products. According to the type of display mode, liquid crystal displays can be 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 double refraction), OCB (optical compensated bend), IPS (in-plane switching, coplanar transition), FFS (fringe field switching, edge field switching), VA (vertical alignment, vertical alignment) and PSA (polymer stable al...
