Claim:
1. A radiation-emitting device comprising: a substrate, at least one layer sequence arranged on the substrate and adapted to generate electromagnetic radiation, comprising: at least one first electrode, at least one second electrode, and at least one functional layer between the first electrode and the second electrode, wherein the functional layer is adapted to generate the electromagnetic radiation in a switched-on operating state, a plurality of transparency regions including at least one transparency region transparent to at least one partial spectrum of electromagnetic radiation of visible light at least in a switched-off operating state, and all transparency regions of the plurality of transparency regions together occupy less than 30% of a total surface area of the radiation-emitting device perpendicular to a viewing axis, and at least one non-transparency region non transparent to the partial spectrum of electromagnetic radiation, wherein the transparency region and the non-transparency region are arranged such that electromagnetic radiation from the partial spectrum can pass through the radiation-emitting device through the transparency region, in a switched-off operating state of the radiation-emitting device, the transparency regions are image-transmissive or viewing-transmissive to visible light, in a switched-off operating state of the radiation-emitting device, the non-transparency region is translucent, but not image-transmissive or viewing-transmissive to visible light, the layer sequence comprising the at least one functional layer is arranged partly in the transparency regions and partly in the non-transparency region, and coupling-out elements are arranged in the at least one non-transparency region, the coupling-out elements being formed by at least one of:
