  • Patent number: 4418118
    Abstract: In the present application, an electroluminescence structure is described which comprises, among other things, a first electrode layer (2) prepared by means of the thin film technique, and a second electrode layer (7, 7') prepared by means of a thick film technique, as well as a luminescence layer (4) disposed between the electrode layers. The use of a thick film directly as the electrode of a thin film structure causes problems resulting from inhomogeneous contact of the thick film material. According to the invention, these problems have been solved so that between the second electrode layer (7, 7') and the luminescence layer (4), a very thin additional layer (6) of resistive material is disposed which is bounded by the second electrode layer (7, 7') and which forms a spreading resistance for the point contacts of the conductive particles in the second electrode layer (7, 7'). In this resistance the inhomogeneous current density is homogenized before reaching the luminescence layer (4).
