Abstract

In one embodiment the organic light-emitting diode includes a substrate having a substrate upper side, an electrically conductive grid structure for a current distribution and an electrically conductive particle layer, which are located at the substrate upper side. The grid structure may be embedded in the particle layer. An organic layer sequence for generating the radiation is located directly on the particle layer. A covering electrode is attached to the organic layer sequence. The particle layer comprises scattering particles having a first average diameter and electrically conductive particles having a smaller second average diameter. The scattering particles are densely packed together with the conductive particles. The particle layer forms, together with the grid structure, a substrate electrode for the organic layer sequence.
