Abstract
A method of fabricating a light extraction substrate for an organic light-emitting diode (OLED) with which the scattering distribution of light that is emitted from the OLED can be artificially controlled. The method includes the step of forming a light extraction layer by depositing an inorganic oxide at least twice on a base substrate, thereby controlling a structure of a texture formed on a surface of the light extraction layer.
