摘要： The present application provides a liquid crystal material, a method of fabricating a liquid crystal display panel, and a liquid crystal display panel. The liquid crystal material of the present application includes liquid crystal molecules, polymerizable monomers and a vertical alignment agent, the polymerizable monomers and the vertical alignment agent can occur a polymerization under ultraviolet irradiation to form a polymer, while the polymer deposits on a substrate to form a polymer film capable of replacing the PI alignment film; so that an alignment process of the liquid crystal is simplified, a cost is economized. The method of fabricating the liquid crystal display panel of the present application eliminates the fabricating process of the alignment film, the method has simple process and low cost. The liquid crystal display panel utilizes the polymer film, which is obtained by polymerizing the polymerizable monomers and the vertical alignment agent, to replace the alignment film, that not only meets the aspect of liquid crystal alignment, but also prevent impurity ions in the TFT and CF substrates to diffuse into the liquid crystal layer, so as to greatly enhance quality of the panel, and to have a low fabricating cost.
