Substrate for organic electronic device
First Claim
1. A substrate for an organic electronic device, comprising a base layer;
- a light scattering layer and an electrode layer in this order,wherein the light scattering layer contacts the base layer,wherein the electrode layer extends beyond the entire peripheries of the light scattering layer,wherein the light scattering layer comprises a matrix material and a scattering region, wherein the matrix material is a polysiloxane, a poly(amic acid), a polyimide, a cardo resin having a fluorene ring, urethane, epoxide, or a polyester or acrylate based thermo-curable or photo-curable monomeric, oligomeric or polymeric organic material,wherein a formation area of the electrode layer is broader than a formation area of the light scattering layer, and the electrode layer is formed also on the surface of the base layer on which the light scattering layer is not formed.

Abstract
The present application relates to a substrate for an organic electronic device, an organic electronic device, a method of preparing the substrate or the device, and a lighting apparatus. The substrate for an organic electronic device of the present application may, for example, be used to fabricate an organic electronic device, to which foreign substances such as moisture and oxygen are not permeated, and which has enhanced durability and superior light extraction efficiency. If the organic electronic device includes an encapsulation structure, the substrate may be stably attached to the encapsulation structure, and a surface hardness of outside connector part of the organic electronic device may be maintained to an appropriate level.
