  • Patent number: 10249847
    Abstract: An organic light-emitting diode provides a substrate having a top side and one or a plurality of substrate side surfaces running transversely to the top side and connected thereto via a substrate edge; and an organic layer sequence applied to the top side with an emitter layer, which generates electromagnetic radiation coupled out from the diode via a luminous surface during intended operation of the diode. In a plan view of the luminous surface, the sequence adjoins at least a partial region of substrate edge(s), and in the region the luminous surface extends at least as far as the corresponding edge. An encapsulation formed in an uninterrupted and continuous fashion is applied to the sequence. The encapsulation, at least in the region of the edge adjoining the sequence, is led onto the associated substrate side surface, at least partly covers the latter and is in direct contact with the surface.
