Abstract

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.
