Claim:
1. A substrate for an organic electronic device, comprising: a base layer; and a scattering layer that is on the base layer and that comprises a binder comprising poly(amic acid) and a scattering particle, of which a refractive index is different from that of the binder, wherein the difference in refractive index between the scattering particle and the binder is from 0.5 to 4.0, wherein the scattering particle has a refractive index of 2.1 to 3.5 and the binder has a refractive index of 1.7 or more with respect to light having a wavelength of 633 nm, wherein the scattering particle forms a single layer in the scattering layer, and wherein the poly(amic acid) has a light transmittance of 80% or more in a visible region.
