Organic light-emitting device

摘要

An organic light-emitting device includes a substrate, on which a transparent electrode and a further electrode are applied. An organic light-emitting layer is arranged between the electrodes. At least one optical scattering layer is arranged on a side of the transparent electrode facing away from the organic light-emitting layer.

1. An organic light-emitting device comprising:
a substrate; a transparent electrode overlying the substrate; a further electrode overlying the substrate; an organic light-emitting layer between the transparent electrode and the further electrode; an optical scattering layer arranged on a side of the transparent electrode facing away from the organic light-emitting layer; and a contact element, wherein at least one of the transparent electrode and the further electrode is electrically contacted by the contact element, wherein the optical scattering layer comprises a matrix material and scatter particles having a refractive index different from the matrix material, wherein the scatter particles have a concentration that increases as a distance from the contact element increases, and wherein the optical scattering layer has a varying thickness.
