Beschreibung
Zusammenfassung:	The present invention relates to a light extraction substrate for an organic light emitting element, a method for manufacturing the same, and an organic light emitting element comprising the same and, more particularly, to a light extraction substrate for an organic light emitting element exhibiting a good light extraction efficiency, a method for manufacturing the same, and an organic light emitting element comprising the same. To this end, the present invention provides a light extraction substrate for an organic light emitting element, a method for manufacturing the same, and an organic light emitting element comprising the same, the light extraction substrate comprising a first light extraction layer having a plurality of pores formed therein and made of a first metal oxide doped with a dopant; and a second light extraction layer formed on the first light extraction layer and made of a second metal oxide which has a different atomic diffusion rate compared to the first metal oxide.
