Abstract (en)
[origin: WO2007076913A1] The invention relates to relates to OLEDs which comprise at least one substrate, a first electrode, at least one organic light-emitting layer and a second electrode, either the substrate and the first electrode, the second electrode or the substrate, the first and the second electrode being transparent. The invention is characterized in that at least one transparent layer is arranged on the substrate and/or the transparent second electrode. Said layer contains transparent, preferably spherical particles which protrude at least partially from the at least one layer. The invention also relates to a method for producing the OLEDs and to their use, especially in lighting devices and displays.
