Abstract:
Electroluminescent device comprising:a first electrode and a second electrode allowing an at least partial passage of light, at least one layer of organic semiconductor showing an electroluminescence by charge injection, a supporting substrate consisting of a metal or metallic alloy, and an electric current source connected to the electrodes in an electrically conductive manner, said substrate having two opposite surfaces comprising an electrically conductive surface which supports said device and a surface which is electrically insulated from the outside, the substrate supporting on said electrically conductive surface as successive layers: the first electrode, which is continuously or alternatively a negative electrode, said at least one layer of organic semiconductor showing an electroluminescence by charge injection, and said second electrode allowing an at least partial passage of light, which is continuously or alternately a positive electrode.
