Abstract
A display device includes: pixels arranged in a matrix; a plurality of write signal lines for selecting a pixel row to which a data voltage is to be written; a gate driver that supplies a gate signal; a plurality of data signal lines for writing the data voltage; a data driver that supplies the data voltage; a data selector circuit that supplies, per at least one data signal line by time division, the data voltage; and a controller. Each of the pixels includes a light-emitting element, a capacitor element, and a drive transistor that supplies a current in accordance with the voltage held by the capacitor element to the light-emitting element. The controller causes the gate driver and the data driver to perform an initialization operation on pixels in a second pixel row after a period during which a write operation is performed on pixels in a first pixel row.
