Abstract: The present invention provides a liquid crystal blend having a higher perpendicular dielectric constant, as well as a liquid crystal display panel and a liquid crystal display device comprising the liquid crystal blend. Since the liquid crystal blend of the present invention contains negative liquid crystal material and has a perpendicular dielectric constant between 3.5 to 4.5, it can improve the transmittance of the liquid crystal layer obtained thereby, compared with the liquid crystal blend without negative liquid crystal material, while other relative properties thereof such as clearing point, response time of the display obtained therefrom, and image sticking at high temperature can also meet the requirements of liquid crystal devices.
