Abstract:
An organic light emitting diode and a method for manufacturing the same. The organic light emitting diode includes an anodic conductive layer, an organic EL layer, and a cathodic conductive layer formed from Ag or an alloy of Ag, or the like, sequentially laminated on a substrate, such that a two-dimensional lattice structure is provided on a surface of the cathodic conductive layer on an organic EL layer side, an extraction wavelength and a distance between centers of concave portions or convex portions in the two-dimensional lattice structure are within a region surrounded by specific coordinates in a graph illustrating a relationship between the light extraction wavelength and the distance, and the depth of the concave portions or a height of the convex portions is 12 nm to 180 nm.
