Claim Text:
1. An organic electroluminescence display device comprising: an organic electroluminescence layer; a pixel electrode and a common electrode stacked to sandwich the organic electroluminescence layer; a thin-film transistor; a first insulating layer that covers a semiconductor layer and a gate electrode of the thin-film transistor; a current supply line electrically connected to one of a source electrode and a drain electrode of the thin-film transistor; a first wire provided on the first insulating layer to electrically connect another of the source electrode and the drain electrode of the thin-film transistor which is not electrically connected to the current supply line, and the pixel electrode, wherein the first wire comprises a first material; a second wire provided on the first insulating layer to be electrically connected to the gate electrode of the thin-film transistor, wherein the second wire comprise the first material; a data line for transmitting a control signal to the gate electrode of the thin-film transistor via the second wire; a conducting film formed on the first wire and the second wire, wherein the conducting film comprises a second material, and an oxidation rate of the second material is less than an oxidation rate of the first material; and a second insulating layer formed on the conducting film and under the pixel electrode, wherein the conducting film and at least one of the pixel electrode, the first wire or the second wire are located to overlap above the first insulating layer in electrical insulation so that a capacitor that retains the control signal is formed between the first wire and the second wire.
