摘要： Disclosed are transparent, organic EL devices comprising an positive electrode, a negative electrode and an organic layer including an organic light-emitting layer as sandwiched between the two electrodes, in which the negative electrode is comprised of an electron injection electrode layer and an amorphous transparent conductive film, and the electron injection electrode layer is adjacent to the organic layer, or in which the negative electrode is comprised of an electron injection electrode layer, a transparent conductive film and a thin metal film having a specific resistance of not larger than 1 x 10 -5 Ω·cm, as laminated in that order with the electron injection electrode layer being adjacent to the organic layer, and a thin transparent film is formed outside the negative electrode. 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.
