Abstract
An electro-optically active organic diode has anode and cathode electrodes, an electro-optically active organic layer between the electrodes, and a charge carrier organic layer between the electro-optically active organic layer and the cathode electrode layer. The charge carrier organic layer is formed of a highly doped organic semiconductor material. A short protection layer is arranged between the cathode electrode layer and the charge carrier organic layer. The short protection layer is formed of an inorganic semiconductor material.
