Abstract
The invention relates to an organic light-emitting diode comprising, on a substrate, generally one lower electrode followed by a flat conductive organic layer a doped organic layer, upon which an organic light-emitting layer is placed, and an upper electrode, which is placed upon this organic light-emitting layer and which is essentially transparent to the light produced in the light-emitting layer. The lower electrode and the flat organic layer serve as a cathode. The doped layer makes it possible to use a hole-conductive material for the flat layer.
