Zusammenfassung:A display device includes: a display unit including a plurality of pixels; a first power supply to generate a first power voltage to the display unit; a second power supply to generate a second power voltage to the display unit; and a signal controller controls the first power supply to supply the first power supply voltage to the display unit when a low luminance image is displayed on the display unit, and when the first power supply voltage is supplied and a predetermined period elapses, the second power supply unit is controlled to stop supplying the second power supply voltage to the display unit. Therefore, it is necessary to consume power with high efficiency even when light is emitted with low luminance. 표시 장치는 복수의 화소를 포함하는 표시부, 표시부에 제1 전원 전압을 공급하는 제1 전원 공급부, 표시부에 제2 전원 전압을 공급하는 제2 전원 공급부, 그리고 표시부에 저휘도 영상이 표시되는 때, 표시부에 제1 전원 전압을 공급하도록 제1 전원 공급부를 제어하고, 제1 전원 전압이 공급되고 소정 기간이 경과되면, 표시부로의 제2 전원 전압 공급을 중지하도록 제2 전원 공급부를 제어하는 신호 제어부를 포함한다.
