AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1-14 is confirmed.
1. An optoelectronic device, comprising:
an organic layer sequence which emits an electromagnetic radiation having a first wavelength spectrum during operation; and
a structured layer disposed downstream of the organic layer sequence in a beam path of the electromagnetic radiation emitted by the organic layer sequence and including first and second regions;
wherein the first regions each include a wavelength conversion layer configured to convert at least partially electromagnetic radiation having a first wavelength spectrum into an electromagnetic radiation having a second wavelength spectrum;
wherein the second regions each include a filter layer which is at least partially opaque to an electromagnetic radiation having a third wavelength spectrum which corresponds to at least one part of the second wavelength spectrum;
wherein the first and second regions of the structured layer are arranged laterally in a beam path of the optoelectronic device; and
wherein the filter layer is transparent to the electromagnetic radiation having the first wavelength spectrum.
