  • Organic electroluminescent element and organic electroluminescent device including the same
    Patent number: 7495387
    Abstract: An emitting device in an organic electroluminescent device is disclosed, in which a lower electrode pattern is formed on a substrate, an emitting layer pattern is formed on the lower electrode pattern, and a transparent electrode is formed on the emitting layer pattern and an emitting body having a structure in which an organic thin film emits light when an application current is applied to it. The pattern of the transparent electrode completely covers and is larger than that of the lower electrode. The pattern of the transparent electrode is formed over the entire area of the pattern of the lower electrode.

  • Emitting body, emitting device, and emitting display device
    Publication number: 20040245937
    Abstract: An emitting device in which a lower electrode pattern is formed on a substrate, an emitting layer pattern is formed on the lower electrode pattern, and a transparent electrode is formed on the emitting layer pattern and an emitting body having a structure in which an organic thin film emits light when an application current is applied to it are disclosed. The pattern of the transparent electrode is larger than that of the lower electrode. The pattern of the transparent electrode is formed over the entire area of the pattern of the lower electrode. The pattern of the transparent electrode is made larger than that of the luminous layer. The pattern of the transparent electrode is formed over the entire area of that of the luminous layer.
