Abstract
Disclosed are an inorganic fine particle scattering film and a manufacturing method thereof, wherein an inorganic fine particle layer comprising pores is formed on a light emitting device interface or a transparent substrate so as to achieve a high light extraction effect through a light scattering effect, and a planarizing layer is formed on the inorganic fine particle layer so as to show a high flatness and a high hardness. The disclosed inorganic fine particle scattering film is excellent in a light extraction effect, flatness and hardness and thus can be applied in the various fields such as an image display device, a lighting element, a solar cell.
