Abstract: A viewing angle expansion film, a method for preparing the same, and a display device are provided. The viewing angle expansion film includes a first film layer having a flat layer, a plurality of first projections, and a plurality of second projections, and a second film layer disposed on the first film layer. The plurality of first projections and the plurality of second projections are arrayed on the flat layer. The second film layer is filled in gaps between the first projections and the second projections adjacent to the first projections, gaps between adjacent first projections, and gap between adjacent second projections. A refractive index of the second film layer is greater than a refractive index of the first film layer.
