Claims

[Claims for Utility Model Registration] An insulating layer, a light-emitting layer, and a transparent conductive film are sequentially formed on a back electrode, and are sealed from above and below with a moisture-proof film, and the light-emitting layer, the insulating layer, and the back In a distributed EL element in which a lead wire for taking out the electrode is connected to an auxiliary electrode on the transparent electrode side provided on the transparent conductive film in a notch that vertically penetrates the electrode, the light-emitting layer and the transparent electrode are provided. A dispersion type EL device, characterized in that an insulating film is formed in a region of the transparent electrode facing the periphery of the notch portion between the transparent electrodes.
