Claim:
A thin-film transistor array device that is stacked with an electroluminescence layer, with an interlayer insulating film interposed between the electroluminescence layer and the thin-film transistor array device, the thin-film transistor array device comprising: a substrate; a first line above the substrate; a second line crossing the first line; a first transistor above the substrate and including a gate electrode, a first electrode, and a second electrode; a second transistor above the substrate; a passivation film between the interlayer insulating film and both the first transistor and the second transistor; a conductive oxide film below the passivation film; and a relay electrode above the passivation film, the relay electrode being a relay between a first conductive material in a same layer as the first electrode and a second conductive material in the electroluminescence layer, the relay electrode being electrically connected to the first conductive material via a first hole in the passivation film, wherein the first transistor and the second transistor are bottom-gate transistors, the first line is below the passivation film and electrically connected to one of the gate electrode and the first electrode, the first line being in the same layer as the first electrode, the second line is above the passivation film and electrically connected to an other of the gate electrode and the first electrode, the second line being in a different layer than the first electrode, a terminal to which an external signal is input is in a periphery of the substrate and in the same layer as the first electrode, the external signal being for driving one of the first line and the second line, the conductive oxide film covers an upper surface of the terminal and is between the relay electrode and the first conductive material at least at a bottom of the first hole, the conductive oxide film electrically connecting the relay electrode and the first conductive material, and the relay electrode is in a same layer as the second line above the passivation film and comprises a same material as the second line.
