Claim:
1. A method for producing an optoelectronic assembly which comprises a first optoelectronic component and at least a second optoelectronic component, which is connected in series with the first optoelectronic component, the method comprising: forming a first electrically conductive layer on a substrate, forming a second electrically conductive layer on the first electrically conductive layer, applying an insulator material in a structured way onto the second electrically conductive layer and the substrate, in such a way that at least a first insulator region, which electrically insulates a first component region for arrangement of the first optoelectronic component from a second component region for arrangement of the second optoelectronic component, a second insulator region, which electrically insulates the second component region from a first contact region, a third insulator region, which is arranged on a side of the first component region facing away from the first insulator region, and a fourth insulator region, which is arranged between the first and second insulator regions on a side of the second component region facing away from the second insulator region, are formed by the insulator material, wherein a third contact region is formed between the first insulator region and the fourth insulator region, forming a first optically functional layer in the first component region and a second optically functional layer is formed in the second component region, and applying an electrically conductive electrode layer in a structured way onto the optically functional layers and the first and third contact regions, in such a way that the first optically functional layer is electrically coupled to the third contact region and the second optically functional layer is electrically coupled to the first contact region, wherein the second electrically conductive layer is removed in the first and second component regions before the application of the optically functional layers, and the optically functional layers are applied onto the first electrically conductive layer after the removal of the second electrically conductive layer in the first and second component regions, and wherein a protective layer is applied in a structured way onto the second electrically conductive layer after the structured application of the insulator material and before the removal of the second electrically conductive layer in the first and second component regions, in such a way that the contact regions are covered with the material of the protective layer, the protective layer protects the contact regions during the removal of the second electrically conductive layer, so that the second electrically conductive layer is preserved in the contact regions, and the protective layer is removed after the removal of the second electrically conductive layer in the first and/or second component region.
