摘要：
The present invention is a method of forming an optical film including the following steps: providing a first film of a first material, extruding a second material to form a second film in a molten state; maintaining the second film in a molten state; bringing the first film proximate the molten second film; patterning the molten second film to form a plurality of structures, the structures defining a plurality of cavities therebetween; and solidifying the molten second film.
