Zusammenfassung:	The present invention relates to a display device and a driving method thereof. The display device includes: an LDO regulator which provides a second power voltage to a first power line during a first period of one frame; a buck converter which provides a first power voltage to the first power line during a third period of the one frame; and a pixel connected to the LDO regulator and the buck converter through the first power line. A voltage level of the second power voltage is equal to a voltage level of the first power voltage. Therefore, when the display is turned on/off, the output of the LDO regulator is supplied to an ELVDD power supply to minimize an effect of noise and increase pixel characteristic sensing accuracy. 본 발명은 표시 장치 및 그 구동 방법에 관한 것으로서, 한 프레임의 제1 기간 동안 제1 전원 라인에 제2 전원 전압을 제공하는 LDO 레귤레이터, 한 프레임의 제3 기간 동안 상기 제1 전원 라인에 제1 전원 전압을 제공하는 벅 컨버터 및 제1 전원 라인을 통해서 LDO 레귤레이터 및 벅 컨버터에 공통적으로 연결된 화소를 포함하고, 제2 전원 전압의 전압 레벨은 제1 전원 전압의 전압 레벨과 동일하다.
