Liquid crystal lens and preparation method thereof

The invention discloses a liquid crystal lens and a preparation method thereof, and the preparation method comprises the steps: manufacturing an imprinting structure corresponding to a required surface shape on a mold pressing surface of a mold; coating a material with a prefabricated surface shape on the surface of a base material, and stamping a required surface shape on the material with the prefabricated surface shape by using the mold; the prefabricated surface shape material is cured and formed; the base material and the prefabricated surface shape material are attached to a substrate, and the liquid crystal lens is manufactured. The problem that the prefabricated surface shape is prone to deformation is solved, and the optical quality of the liquid crystal lens is improved. 本发明公开了一种液晶透镜及其制备方法，其中，所述制备方法包括：在模具的模压面制作与所需面形相对应的压印结构；在基材的表面涂布预制面形材料，并使用所述模具在所述预制面形材料上压印出所需的面形；将所述预制面形材料固化成型；采用所述基材及所述预制面形材料贴合于基板上，并制作液晶透镜。本发明解决了预制面形容易变形的问题，实现了液晶透镜的光学质量的提高。
