摘要： The invention relates to an OLED with a layered construction that is located on a substrate, said construction at least comprising an anode, a cathode and a functional layer situated therebetween. At least one electrode, either the anode or the cathode, is permeable to the light emitted by the functional layer and is situated on the light-emitting side (emission side) of the layered construction. The colour conversion layer or layers has/have quantum dots and is/are situated on the emission side, above or below the layered construction.
