Abstract
The invention is directed to an organic EL device with a flattened first electrode, and a method of fabricating the same. After an ITO film serving as the first electrode is formed on a glass substrate , a combined flattening and leveling film is formed and patterned to form a combined flattening and leveling film . In addition, the ITO film is over-etched to form an ITO film together with an undercut portion . After a flattening film or an insulating film is coated all over the surface, a large portion of the flattening film and the flattening and leveling film are removed to allow an insulating film formed in the undercut portion to remain at the same thickness as the ITO film
