发明名称 Organic light-emitting display device
摘要 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.
