    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.

Preferably, the transparent conductive film is an amorphous one. The devices have a negative electrode with low resistance and high transparency, and have high luminous efficiency and good durability (wet heat resistance). The light emission can be taken out through the side of the negative electrode of the devices. The devices are usable for high-resolution display.
