Abstract
A method for manufacturing a substrate with a concave-convex structure includes: forming a base material layer on a substrate; forming a base layer having a concave-convex pattern by transferring a concave-convex pattern of a mold to the base material layer; and forming a coating layer by coating the concave-convex pattern of the base layer with a coating material, wherein the coating layer is formed such that a thickness of the coating layer is in a range of 25 to 150% of standard deviation of depth of concavities and convexities of the base layer. The substrate with the concave-convex structure manufactured by this method has good light extraction efficiency and effectively prevents leak current in an organic light emitting diode having this substrate.
