摘要： The invention relates to an electronic device comprising a layer structure of organic layers, wherein said layer structure comprises a p-n-junction between an n-type doped organic layer provided as an organic matrix material doped with an n-type dopant and a p-type doped organic layer provided as a further organic matrix material doped with a p-type dopant, and wherein the n-type dopant and the p-type dopant both are molecular dopants, a reduction potential of the p-type dopant is equal or larger than about 0 V vs. Fc / Fc + , and an oxidation potential of the n-type dopant is equal or smaller than about -1.5 V vs. Fc / Fc + .

摘要： In order to improve the fill factor as well as the efficiency for a structural element on the basis of an organic light-emitting diode facility, a display is proposed comprising a substrate, a first electrode ( 130 ) nearest to the substrate, a second electrode ( 160 ) away from the substrate and at least one light-emitting organic layer ( 150 ) arranged between both electrodes. The light emitted in the active zone transmits through one of the two electrodes whereby the first electrode is pixel-structured and an isolation layer ( 150 ) is arranged between neighbouring pixels. The display according to the invention is characterized in that the isolation layer ( 150 ) is optically coupled with the light-emitting layer ( 150 ), and has optically effective light-scattering and fill factor increasing heterogeneities ( 180, 190 ), whereby the isolation layer is micro-structured to match the pixel structure of the first electrode and is processed onto this. In addition, the invention concerns also a method for the manufacture of such a display.
