Abstract
The present invention discloses a negative dielectric anisotropic liquid crystal composition, characterized in that the liquid crystal composition comprises one or more compounds represented by formula I, one or more compounds represented by formula II, one or more compounds represented by formula III and one or more compounds represented by formula IV, In the liquid crystal molecules of the composition, the van der Waals force therebetween is used as a motive force, such that the liquid crystal molecules generate an attractive force at an appropriate distance and positional relationships, thereby enabling the liquid crystal molecules to have excellent regular alignment characteristics, which is favorable for the liquid crystal molecules to modulate the transmission and blocking of light in the liquid crystal display device.
