Abstract

A method for producing a component is provided, where the component comprises a substrate, which emits at least one electromagnetic radiation in a first wavelength range and an electromagnetic radiation in a second wavelength range within one surface area. Electrodes can be formed within the surface area of the substrate; a first layer stack can be deposited, comprising at least one layer, which causes the emission of the electromagnetic radiation in the first wavelength range, and a cover layer, acting as the first counterelectrode, on the entire surface area; the first layer stack can be removed from a first partial surface area, which comprises at least one electrode; a second layer stack can be deposited, comprising at least one layer, which causes the emission of the electromagnetic radiation in the second wavelength range, and a second cover layer, acting as the counterelectrode, on the entire surface area.
