    摘要： An amorphous electrically conductive oxide such as In—Zn—O-containing amorphous oxide or amorphous ITO is used alone, or a laminate having a two- or three-layer structure constituted of the amorphous electrically conductive oxide and at least a thin metal layer is used, to form a transparent electrode whose side surface has a tapered form and whose top layer is formed of a layer of the above amorphous electrically conductive oxide, an organic single-layer portion or an organic multi-layer portion containing at least an organic light-emitting material is formed on the above transparent electrode, and further, an opposing electrode is formed on the above organic single-layer portion or the above organic multi-layer portion, whereby an organic EL device is obtained. A flattening layer is optionally provided so as to abut on the side surface of the transparent electrode for moderating a height-level difference between the above transparent electrode and the surface of the above substrate. Further, the above organic EL device is used to form an organic EL display panel.
