Claim Text:
1. A method of liquid crystal photo-alignment, which comprises the steps of: providing a liquid crystal layer, the liquid crystal layer doped with reactive monomer; and under influence of an electric field, using radiation light to irradiate on the liquid crystal layer so as to trigger polymerization of monomers to achieve the photo-alignment of the liquid crystal layer; wherein the polymerization of monomers comprising a first stage and a second stage following the first stage, the radiation light having a first illumination in the first stage and having a second illumination in the second stage, and the first illumination being less than the second illumination, wherein the reactive monomer has a first concentration at the beginning of the first stage and has a second concentration at the beginning of the second stage, wherein the second concentration is e wherein the polymerization of reactive monomers further comprises a third stage following the second stage; wherein the radiation light has a third illumination in the third stage, the second illumination is less than the third illumination, and the radiation light irradiates in an uninterrupted manner on the liquid crystal in the third stage.
