Abstract

The present invention relates to an organic light emitting device that includes a layered structure including a substrate, a bottom electrode and a top electrode, wherein the bottom electrode is closer to the substrate than the top electrode, the region between the bottom electrode and the top electrode defining an electronically active region, wherein the electronically active region includes a scattering layer having a thickness of less than 50 nm; and an organic light emitting device additionally having at least one light emitting layer in the electronically active region, and this device can also include a specific chemical compound outside of the electronically active region.
