Abstract
In at least one embodiment of the organic light-emitting diode (), this comprises a mirror () and an organic layer sequence (). The organic layer sequence () contains a first active layer () for producing first radiation and at least two second active layers () for producing second radiation. The active layers () are arranged one above the other in a main direction (x) away from the mirror (). A charge generation layer () is located in each case between two adjacent active layers (). The second active layers () each have the same at least two radiation active organic materials. The first active layer () has a radiation active organic material which is different therefrom.
