Abstract
A thin-film transistor array includes first and second bottom-gate transistors, a passivation film, a conductive oxide film below the passivation film, and a relay electrode between a first conductive material in a same layer as a first electrode of the first transistor and a second conductive material in an electroluminescence layer. A first line is in a layer lower than the passivation film and a second line is above the passivation film. A terminal to which an external signal is input is provided in a periphery of the substrate in the same layer as the first electrode. The conductive oxide film covers an upper surface of the terminal and is between the relay electrode and the first conductive material. The relay electrode is formed in a same layer and comprises a same material as the second line.
