  • Patent number: 7909672
    Abstract: A scanning line, a signal line, a first current supply line, and a second current supply line are formed on a glass substrate, a first electrode is formed on the wiring layer comprising the above members, an organic layer comprising a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer is formed on the first electrode, a second electrode is formed as cathode on the electron injection layer, the first electrode as anode is connected to a plus terminal of a power source through the driving devices and the first current supply line, whereas the second electrode as cathode is connected to a minus terminal of the power source, and is connected to the second current supply line in the display region of each pixel, with a contact hole serving as a feeding point, whereby wiring resistance due to the second electrode is reduced, and variations in the brightness of a panel is reduced.

  • Patent number: 6864638
    Abstract: A scanning line, signal line, first current supply line, and second current supply line are formed on a glass substrate. A first electrode is formed thereon; and, an organic layer, including a hole transport layer, light-emitting layer, electron transport layer, and electron injection layer is formed on the first electrode. A second electrode is formed as a cathode on the electron injection layer. The first electrode, serving as an anode, is connected to a plus terminal of a power source through driving devices and first current supply line, whereas the second electrode is connected to a minus terminal of the power source and is connected to the second current supply line in the display region of each pixel, with a contact hole serving as a feeding point, whereby the wiring resistance of the second electrode is reduced, and variations in the brightness of the panel is reduced.
