Abstract: An organic EL display device has a pixel electrode and a common electrode, a first insulating layer that covers a thin-film transistor, a first wire provided on the first insulating layer to electrically connect the thin-film transistor and the pixel electrode, a second wire provided on the first insulating layer to be connected to a gate electrode of the thin-film transistor, and a conducting film formed on the first wire and the second wire from a material on which an oxide film is harder to be formed than those of the first wire and the second wire. At least one of the pixel electrode, the first wire, and the second wire and the conducting film are located to overlap above the first insulating layer in electrical insulation so that a capacitor that retains a control signal is formed between the first wire and the second wire.
