ABSTRACT:
A device for emitting electromagnetic radiation includes a substrate, at least one active layer of a radiation-emitting organic material, a cover, and a seal between the substrate and the cover so that an interior space between the substrate and the cover is closed off in a gas-tight manner. The seal protects the active layer against humidity from the ambient air. By using simple and cost-effective measures, the device thus has a long service life and benefits from all advantages of organic, light-emitting diodes.
