ABSTRACT:
The object of the present invention is to provide an organic thin film EL device that has an improved close adherence of a hole injection electrode to an organic thin film layer and a long life, maintaining uniform luminance and minimized performance deterioration over the lapse of time. The organic thin film EL device, which includes an electron injection electrode and a hole injection electrode with an organic thin film layer placed therebetween, has a part or the whole of the hole injection electrode formed of a carbon film. In addition, the carbon film is formed by a sputtering method.
