Abstract
A display device includes a plurality of pixels respectively including, a light emitting element, a driving transistor configured to control driving current to the light emitting element, and a storage capacitor configured to be written voltage corresponding to a gradation value on and hold the voltage and configured to apply display voltage depending on the voltage corresponding to the gradation value between a gate and a source of the driving transistor. The display device further includes a stress voltage application unit configured to apply a stress voltage having a voltage value outside a range of a value capable of taking the display voltage between the gate and the source of the driving transistor.
