Abstract
The present application discloses to provide a display device capable of displaying an image with a luminance depending on a data signal by controlling pulling of a gate voltage of a driving transistor occurring when a writing period starts and ends and a driving method of the display device. A pixel circuit including a compensation circuit compensating variation of a threshold value of a driving transistor is provided with a boost capacitor including a MOS capacitor between a node connected to a gate terminal of the driving transistor and a scanning line. A current value of a drive current is controlled by the driving transistor by using the pulling of the potential of the node being different between a case that a low level voltage is applied the scanning line connected to the boost capacitor and a case that a high level voltage is applied.
