Abstract
A material of alignment film, a method of fabricating a liquid crystal display panel, and a liquid crystal display panel are provided. The material of alignment film is obtained by mixing a polymerizable monomer in the polyamic acid solution, thus is easy to fabricate. The method of fabricating the liquid crystal display panel obtains an alignment film including a polyimide film and polymer protrusions located on a surface of the polyimide film by coating the material of alignment film on a substrate, and going through a series of processes; the alignment film can allow liquid crystal molecules arrange in vertical alignment and generate a pre-inclination angle, and a risk of the polymerizable monomer contaminating the liquid crystal molecules does not exist, so as to enhance quality of the liquid crystal display panel. The liquid crystal display panel has a simple structure and good alignment effect, and has excellent display quality.
