1. A method of manufacturing a substrate for an OED, comprising:
- forming a conductive pattern directly on a release surface of a releasable substrate;
forming a precursor material layer for an adhesive layer directly on the conductive pattern and a surface of the releasable substrate having the conductive pattern, the precursor material layer comprising a high refractive coating solution comprising an organic or inorganic binder and scattering particles;
laminating a second substrate directly on the precursor material layer; and
converting the precursor material layer into an adhesive layer,wherein the conductive pattern is formed to be exposed to a surface of the adhesive layer opposite to a surface of the adhesive layer attached to the second substrate, and the surface of the adhesive layer, which includes the exposed conductive pattern, is a planarized surface having a maximum height roughness of 1 μ
m or less, andwherein the conductive pattern is formed to have a ratio of an area of the conductive pattern exposed to the planarized surface to be 0.1% to 40% of a total area of the planarized surface, for the substrate for an OED to have a sheet resistance of the planarized surface of 5 Ω

Abstract
The present invention relates to a substrate for an organic electrode device, a manufacturing method thereof, and an organic electronic device. An exemplary substrate of the invention, if an organic light emitting element is formed on an upper part of the substrate, can obtain luminance with high emission and uniformity by efficiently controlling the surface resistance of an electrode even when the device is configured into larger sizes.
