LIGHT EXTRACTION SUBSTRATE FOR ORGANIC LIGHT-EMITTING DIODE, MANUFACTURING METHOD THEREFOR, AND ORGANIC LIGHT-EMITTING DIODE INCLUDING SAME

The present invention relates to a light extraction substrate for an organic light-emitting diode, a manufacturing method therefor, and an organic light-emitting diode including the same and, more specifically, to: a light extraction substrate for an organic light-emitting diode, which can improve light extraction efficiency of an organic light-emitting diode by reducing a distance between an organic light-emitting layer and a light extraction layer of the organic light-emitting diode more than a conventional distance therebetween; a manufacturing method therefor; and an organic light-emitting diode including the same. To this end, the present invention provides a light extraction substrate for an organic light-emitting diode, a manufacturing method therefor, and an organic light-emitting diode including the same, the light extraction substrate comprising: a base substrate; a mesh net-type metal material formed on the base substrate; matrix layers formed on the base substrate, wherein the matrix layers are respectively formed in a plurality of spaces partitioned by the mesh net-type metal material; and a plurality of light scatterers dispersed inside the matrix layers.
