Display device

A display device comprising:

• 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;
• and 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;
• wherein the stress voltage application unit applies one of a high voltage value, which has a voltage value higher than an upper limit value of the range of the value capable of taking the display voltage, and a low voltage value, which has a voltage value lower than a lower limit value of the range of the value capable of taking the display voltage, wherein the display device further comprises a relief voltage application unit configured to apply a relief voltage, and wherein the relief voltage has a voltage value lower than the high voltage value when applying the high voltage value, and has a voltage value higher than the low voltage value when applying the low voltage value.
