Abstract
The present application provides a ligand-modified quantum dot material, a method of fabricating a liquid crystal display panel, and a liquid crystal display panel. The ligand-modified quantum dot material of the present application can occur a polymerization with the ligand-modified quantum dot material under ultraviolet irradiation to form a polymer, while the polymer deposits on a substrate to form a polymer film, which can replace the PI alignment film, so that an alignment process of liquid crystal is simplified, and a cost is economized; simultaneously, display quality of a liquid crystal display panel can be improved by the quantum dots anchored in the polymer film. The method of fabricating the liquid crystal display panel of the present application eliminates the fabricating process of the PI alignment film, the method has simple process and low cost, and a liquid crystal display panel obtained thereby has better display quality. The liquid crystal display panel of the present application utilizes the polymer film, which is obtained by polymerizing the ligand-modified quantum dot material and a polymerizable monomer, to replace the PI alignment film, so as to greatly enhan…
