Abstract
Provided is an image display device including: a pixel circuit; a power supply line; a data line for supplying a data signal to the pixel circuit; and a current path control unit. The pixel circuit includes: a light emitting element; a drive transistor for controlling a current flowing to the light emitting element; a storage capacitor provided between the data line and a gate electrode of the drive transistor, for storing a potential difference; and a data line connection switch for connecting one end of the storage capacitor on the gate electrode side of the drive transistor and the data line. Before the data line supplies the data signal, the data line connection switch is turned ON, and the current path control unit interrupts a current path from the power supply line to the one end of the storage capacitor.
