Abstract

A method for forming a fresnel lens includes the following steps. First, a master, which has a surface formed with a corresponding pattern of the fresnel lens, is provided. A first fresnel material layer is then formed on the surface. After that, a second fresnel material layer is formed on the first fresnel material layer, and a transparent substrate is provided on the second fresnel material layer. Finally, the transparent substrate, second fresnel material layer, first fresnel material, and master are pressed together to form the fresnel lens.
