Abstract: A method of manufacturing a light scattering film, the method includes providing a light transmissive base having a film shape. A plurality of holes is defined in the light transmissive base, using a perforating device. Each of the plurality of holes has a diameter ranging from about 100 nm to about 5 μm. A spacing between each of the plurality of holes is about twice to about five times as large as an average diameter of each of the plurality of holes.
