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.
Claims27
A light extraction substrate for an organic light-emitting device, comprising:
- a base substrate;
- a scattering layer disposed on the base substrate, the scattering layer being formed from TiO2, a number of voids, as first light-scattering elements, formed within the scattering layer;
- and
- a planarization layer disposed on the scattering layer,
- wherein the scattering layer is infiltrated by a same material as a planarization-forming material from which the planarization layer is formed.
