Abstract

The invention provides a liquid crystal composition and a liquid crystal display device thereof. The liquid crystal composition comprises at least one compound as shown in a general formula I and at least one polymerizable compound as shown in a general formula II. The liquid crystal composition has the advantages of small polymer layer surface roughness, good low-temperature storage stability, fast angular velocity, low polymer residue, high VHR and good pre-tilt angle stability. When the liquid crystal composition is applied to a liquid crystal display, the display quality of the liquid crystal display can be improved, the production process of a PSA type liquid crystal display can be accelerated, the production efficiency can be improved, the problems of'image viscosity ', 'broken bright spots' and uneven display in the liquid crystal display can be solved, and the liquid crystal composition has high practical application value.

Description

technical field [0001] The invention relates to the field of liquid crystals, in particular to a liquid crystal composition and a liquid crystal display device comprising 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 Birefringence), OCB (optical compensated bend), IPS (in-plane switching, coplanar transformation), FFS (fringe field switching, fringe field switching), VA (vertical alignment, vertical alignment) and PSA (polymer stable alignment, polymer stable alignment)...
