An image display device includes a luminescence element, a capacitor, and a driver having a gate connected to a first electrode of the capacitor and a source connected to an anode of the luminescence element. A power source supplies a reference voltage to the first electrode of the capacitor via a first switch. A data line supplies a signal voltage to the second electrode of the capacitor via a second switch. A third switch connects the anode of the luminescence element to the second electrode of the capacitor. A controller supplies the signal voltage to the capacitor by switching ON the first and second switches when the third switch is OFF, and switches OFF the first and second switches to switch ON the third switch after a voltage corresponding to the signal voltage is held by the capacitor.

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.
