Organic electronic device and substrate for organic electronic device

Abstract

An organic electronic device provided with an organic electronic element on one surface of a substrate, wherein the substrate has a metal layer and an insulating layer overlaid on at least one face side of the metal layer, and the one face of the substrate does not have an irregularity peak having a K value of equal to or lower than −0.07 as calculated by expression (1). In the expression (1), x represents an irregularity peak position when a line roughness analysis is conducted on a 10 μm square on the one face of the substrate with an interval of 2.45 nm, f(x) represents a surface irregularity height (nm) at x, and dx represents an infinitesimal change in x. K=[f(x+dx)−2f(x)+f(x−dx)]/dx2 . . . (1)
