Abstract
An image display device includes: a light-emitting element that emits light corresponding to an amount of current in an emission period; a storage capacitor to which a display potential is supplied to one end thereof before the emission period and which stores a voltage corresponding to the display potential; a driving transistor that adjusts an amount of current flowing in a drain electrode thereof in accordance with the voltage stored by the storage capacitor; a lighting control switch which is connected in series with the light-emitting element from the drain electrode of the driving transistor and which is turned on in the emission period; and a discharge switch that connects a node in a current path from the driving transistor to the light-emitting element, through which a current flows when the lighting control switch is turned on, to a wiring that supplies a discharge potential before the emission period.
