Abstract
A radiation-emitting device has a radiation-emitting component with a layer stack with an active region that is formed for the emission of electromagnetic radiation. A microstructure layer is mechanically coupled to the layer stack and has elevations that extend away from the layer stack. A protective layer has a planar side facing away from the microstructure layer and is arranged on a side of the microstructure layer facing away from the layer stack.
