Abstract

The present invention relates to a light extracting substrate for an organic light emitting device, a method of manufacturing same, and an organic light emitting device including same and, more particularly, to: a light extracting substrate for an organic light emitting device, the light extracting substrate being capable of not only maximizing the light extraction efficiency of an organic light emitting device through an undulating structure formed on a surface contacting the organic light emitting device and through a scattering structure having a maximized refractive index difference, but also of being manufactured through a simple process constituted of anode oxidation and wet coating; a method of manufacturing same; and an organic light emitting device including same. To this end, the present invention provides a light extracting substrate for an organic light emitting device, a method of manufacturing same, and an organic light emitting device including same, the light extracting substrate characterized by comprising: a base substrate; a plurality of nanotubes formed on the base substrate; and a coating layer formed on the plurality of nanotubes, sealing the top of the plurality of nanotubes, forming an air layer inside each of the plurality of nanotubes, and having undulations formed on the surface thereof due to capillary action induced by the plurality of nanotubes during forming.
