Abstract:
The present invention provides a light extraction substrate for an organic light emitting device, comprising: a base substrate; a scattering layer formed on the base substrate and made of TiO2; a plurality of first light scatterers formed inside the scattering layer and having a porous form; and a flat layer formed on the scattering layer, wherein the scattering layer is internally permeated by a part of the materials constituting the flat layer.
