Abstract

An OLED is thus specified which includes a layer construction comprising at least an anode, a cathode and a functional layer arranged in between, the layer construction being arranged on a substrate. At least one electrode, selected from the anode and cathode, is transmissive to the light emitted by the functional layer and is arranged on the light-emitting side, emission side, of the layer construction. The at least one color conversion layer has quantum dots and is arranged on the emission side above or below the layer construction.
