ABSTRACT:
The present invention provides a transparent substance formed with a plurality of continuous half-spherical convexes having a diameter of 25˜1,000 nm on its first main surface; an organic light-emitting device comprising a substrate, a first electrode, an organic material layer(s) and a second electrode, sequentially, characterized by having a plurality of continuous half-spherical convexes having a diameter of 25˜1,000 nm on the underside of the substrate that does not contact the first electrode and/or the upside of the second electrode that does not contact the organic material layer; and a method for preparing same using a porous aluminum oxide layer forming process.
