Abstract
The present invention relates to a method for manufacturing a light extraction substrate for an organic light-emitting diode and, more specifically, to a method for manufacturing a light extraction substrate for an organic light-emitting diode, which can improve light extraction efficiency of an organic light-emitting diode and can also remarkably reduce a manufacturing process, manufacturing costs, and manufacturing time. To this end, the present invention provides a method for manufacturing a light extraction substrate for an organic light-emitting diode, the method comprising: an ion injection step of injecting, into the inside of the base material, an ion from one side of a base material arranged on a transparent electrode of an organic light-emitting diode, so as to form an ion injection layer inside the base material; and a heat treatment step of forming, inside the base material, a pore layer having a plurality of pores having a different refractive index from that of the base material, through the application of thermal energy to the ion injection layer, wherein the plurality of pores are induced through the gasification of the ion.
