Abstract

An light-emitting apparatus and a method for producing a light-emitting apparatus are disclosed. In an embodiment, the apparatus includes at least one organic device and an outcoupling layer, wherein the at least one organic device emits electromagnetic radiation during operation, wherein the outcoupling layer contains optical structures, and wherein the apparatus has a non-Lambertian radiation distribution curve during operation. The outcoupling layer influences the radiation passing through it in an optically varying manner by the optical structures along a lateral direction in order to produce the non-Lambertian radiation distribution curve.
