Abstract

An organic light-emitting diode includes at least two segments arranged adjacent to one another, a scattering layer that at least partially scatters the light generated in each of the segments, and at least one separating region located in the scattering layer, wherein the separating region has a transmittance for light generated in the segments of at most 20%, the separating region, when viewed in a plan view, is arranged in a transitional region between adjacent segments such that within the scattering layer propagation of light between the segments is suppressed, the segments include organic layer sequences each located between a first electrode and a second electrode, the segments are distant from one another in a direction parallel to the main directions of extension, and the scattering layer directly adjoins the first electrode which is light-transmitting and directly adjoins a transparent layer on a side remote from the first electrode.
