Abstract
An image display apparatus includes a plurality of pixels. Each pixel includes a light emitting device; a drive transistor that has a gate electrode, a source electrode, and a drain electrode. One of the source and drain electrodes are electrically connected to one end of the light emitting device. Each pixel also includes a first switching transistor that electrically connects the gate electrode and the one electrode according to a scan signal, and a capacitor that has first and second electrodes. The first electrode is electrically connected to the gate electrode. The apparatus also includes a data line connected to the second electrode; a data line drive circuit that supplies a brightness potential and a reference potential for the brightness potential to the data line.
