Claim Text:
1. A substrate for an organic electronic device comprising: 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 to planarize an uneven surface of the scattering layer, wherein a refractive index Na of the scattering particles and a refractive index Nb of the planarizing layer satisfy the expression |Na−Nb|≧0.3, and the refractive index Na of the scattering particles is in a range of 2.0 to 3.5 and the refractive index Nb of the planarizing layer is in a range of 1.7 to 2.5.
