Abstract
A light-emitting device includes a first electrode area on a substrate and a functional light-emitting layer on the first electrode area. A second electrode area is disposed on the functional light-emitting layer. A light outlet layer is disposed in a radiation path of the functional light-emitting layer. The light outlet layer incorporates a number of optical elements whose distribution and/or geometrical shape vary across a surface of the light outlet layer.
