A PSA-type liquid crystal composition includes a host liquid crystal A and a polymerizable component B, where the host liquid crystal A includes one or more liquid crystal compounds, and the polymerizable component B includes at least one compound selected from compounds of general formula I-1, general formula I-2 and general formula I-3. A liquid crystal display device includes the PSA-type liquid crystal composition above. The PSA-type liquid crystal composition has better intersolubility, cannot be crystallized at a low-temperature environment, can form a relatively stable pretilt angle after the polymerization of the polymerizable component, avoids the image sticking, and inhibits the occurrence of a display defect, such as Zara Particle, during the polymerization.

PSA-type liquid crystal composition and display device having same

A liquid crystal composition contains: at least one compound of general formula I and at least one polymerizable compound of general formula II. Such a liquid crystal composition has a suitable optical anisotropy, a suitable dielectric anisotropy, and a better pretilt angle consistency while maintaining a relatively high clearing point, and the drop mura is good. When the liquid crystal composition is applied to a PSA liquid crystal display, the liquid crystal composition has an excellent display effect. 

Liquid crystal composition and use thereof

Disclosed are a liquid crystal composition and a liquid crystal display device. The liquid crystal composition comprises at least one compound of general formula I, at least one compound of general formula II, at least one compound of general formula III, and at least one compound of general formula IV. By compounding the four compounds, the composition can have advantages of a wide temperature range of nematic phase, a low viscosity and a low threshold voltage, and the liquid crystal display element can have a short response time and great power saving performance.
