摘要： A light-emitting device comprising a light-emitting layer and a light exit layer. In this case, the light exit layer has a multiplicity of mutually parallel first areas, arranged in an inclined fashion with respect to the light-emitting layer. The light exit layer furthermore has a multiplicity of mutually parallel second areas arranged in an inclined fashion with respect to the light-emitting layer and in an inclined fashion with respect to the first areas. The first areas are transparent and the second areas are reflective to light emitted by the light-emitting layer.

摘要： A radiation emitting device includes a substrate and a layer sequence disposed on top of the substrate. The layer sequence includes a first electrode surface with a first contact for applying a voltage, at least one functional layer that emits radiation during operation, and a second electrode surface. In the layer sequence, a plurality of partial regions is present that is modified in such a way that the emission of radiation visible to an external observer therefrom is interrupted. The distribution density of these partial regions can vary depending on their distance from the contact.
