Abstract:
A substrate including a base substrate; a scattering layer which is formed on the base substrate, includes a binder and scattering particles for scattering light, and has an uneven structure formed on a surface thereof opposite the base substrate; and a planarizing layer which is formed on the scattering layer and has a flat surface formed thereon, is provided. Here, the refractive index Na of the scattering particles and the refractive index Nb of the planarizing layer satisfy the expression |Na−Nb|≧0.3, an organic electronic device including the substrate, and a method of manufacturing the same are provided. Light-extraction efficiency can be improved and the manufacturing process can be simplified without degrading device performance.
