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 an 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.
