Patent number: 8129611Abstract: A light scattering film having the structure which guides electrical signal to a desired position and scatters incident light and the surface of which is substantially flat, and a photoelectric device using the same. The light scattering film includes a medium made of transparent conductive material and a light scatterer embedded in the medium.
