An optical film with touch function includes a substrate, a material layer, a plurality of columnar structures, and a filter electrode layer. The substrate has a carrying surface. The material layer is disposed on the carrying surface of the substrate. Each of the columnar structures is extended from a side of the material layer adjacent to the carrying surface to a side of the material layer away from the carrying surface. A side of each of the columnar structures adjacent to the substrate has a first end surface. The filter electrode layer is disposed between the substrate and the material layer. The filter electrode layer includes a plurality of sensing electrode regions electrically insulated from each other. The filter electrode layer has a plurality of openings, and the openings respectively expose the first end surfaces.
