Abstract
Provided is a method of manufacturing an organic light-emitting diode including forming an anode on a substrate, forming an organic light-emitting layer on the anode, forming a cathode on the organic light-emitting layer, and forming a light scattering film on the cathode. The light scattering film is a polycrystalline dielectric material composed of anisotropic crystals, and a surface roughness Ra of a top surface of the light scattering film is greater than or equal to about 50 nm by an anisotropic crystal growth of particles of the dielectric material.
