Abstract:
1. Organic light-emitting diode having a mirror and having an organic layer sequence comprising: a first active layer which is arranged to produce first radiation, and at least two second active layers which are arranged to produce second radiation, wherein the active layers are arranged one above the other in a main direction away from the mirror, and a charge generation layer is located in each case between two adjacent active layers, wherein the second active layers each have the same at least two radiation active organic materials and the first active layer has a radiation active organic material which is different therefrom, an optical cavity is formed by the mirror and by an optical boundary layer having a jump in the refractive index on a side of the organic layer sequence facing away from the mirror, the cavity has several intensity maxima in the main direction, wherein the active layers are each located in or on one of the intensity maxima in the main direction, a distance between the second active layers is smaller than a distance between the first active layer and the closest second active layer and the second active layers are optimised for mutually different wavelengths.
