Abstract
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.
