Abstract:
A radiation emitting apparatus including a substrate, at least one layer sequence arranged on the substrate and producing electromagnetic radiation in a wavelength range, having at least one first electrode surface, at least one second electrode surface, and at least one functional layer between the first electrode surface and the second electrode surface, wherein the functional layer produces electromagnetic radiation in the wavelength range in a switched-on operating state, and a scatter layer having a first region and a second region, wherein radiation produced by the functional layer is directly incident on the scatter layer only in the first region of the scatter layer, and the scatter layer at least partially scatters radiation incident upon the first region of the scatter layer so that said radiation enters the second region of the scatter layer.
