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.
