본 발명의 표시 장치는 제1 유기 발광 다이오드를 포함하는 제1 화소; 상기 제1 유기 발광 다이오드의 애노드에 공급될 제1 초기화 전압을 생성하는 초기화 전압 생성부; 및 복수의 최대 휘도에 대응하는 복수의 제1 초기화 전압 값이 기록된 제1 룩업 테이블을 포함하고, 목표 최대 휘도에 대한 수신 정보와 상기 제1 룩업 테이블에 기초하여 상기 제1 초기화 전압의 값을 결정하는 타이밍 제어부를 포함한다. A display device includes: a first pixel comprising a first electrode initialization transistor and a first light emitting diode to emit light having a first color, the first light emitting diode comprising a first electrode and a second electrode; and a second pixel comprising a second electrode initialization transistor and a second light emitting diode to emit light having a second color different from the first color, the second light emitting diode comprising a third electrode and a fourth electrode. The second electrode of the first light emitting diode and the fourth electrode of the second light emitting diode are configured to receive a first power voltage. The first electrode of the first light emitting diode is configured to receive a first initialization voltage through the first electrode initialization transistor, and the third electrode of the second light emitting diode is configured to receive a second initialization voltage through the second electrode initialization transistor, the second initialization voltage being different from the first initialization voltage and the first power voltage.
