Abstract
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 including the same, which can shed its dependence on light extraction in a specific wavelength range appearing in a light determining pattern of a cyclical form and induce light extraction in a broader wavelength range. To this end, 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 including the same. The light extraction substrate is disposed on one surface through which light emitted from the organic light-emitting element is outwardly released and comprises: a base substrate; a light determining pattern formed on the base substrate; and a leveling layer formed on the light determining pattern and having a surface contacting the organic light-emitting element, wherein a plurality of air voids having a random shape and size are irregularly distributed on an interface between the light determining pattern and the leveling layer.
