Abstract

The invention relates to a method for producing an organic light-emitting diode (1) comprising the following steps: providing a carrier (3) for the organic light-emitting diode (1), applying a solution (S) comprising a plurality of different emitter materials (E) to the carrier (1), wherein said emitter materials (E) are each formed by a certain type of organic molecule and have electrical charges that differ from each other, applying an electrical field (F), so that the solution is located in the electrical field (F), and drying the solution (S) into a plurality of emitter layers (20) in an organic layer stack (2), while the electrical field is applied, so that the emitter materials (E) are accommodated separately from each other, each in a certain emitter layer (20) of the organic stack (2).
