Abstract
Disclosed are a liquid crystal material, a liquid crystal display panel and a manufacture method of a liquid crystal display panel. The liquid crystal material comprises liquid crystal molecules, and photosensitive vertical alignment material mixed thereamong, and the photosensitive vertical alignment material comprises a head group A, a middle base group Sp, a photosensitive base group B and a tail group R. The head group A is anchored on the substrate so that the entire molecules are aligned perpendicular with the substrate, and a photo reaction takes place to the photosensitive base group B by being irradiated with the ultraviolet light from the tilted direction, which leads to the alignment direction change of the entire molecules to be aligned on the substrate with a certain tilted angle according to the irradiation direction of the ultraviolet light. The liquid crystal molecules at the surfaces of the substrate have a pre-tilted angle.
