Zusammenfassung:	According to the present invention, a display device capable of properly balancing trade-off between consumption power reduction and image degradation comprises: organic light emitting diodes emitting light with gradations constituting a target frame; a power supply voltage supply unit supplying a power supply voltage applied to one electrode of the organic light emitting diodes; and a power supply voltage determination unit extracting target gradations in descending order based on the highest gradation among the gradations and determining the magnitude of the power supply voltage based on the number of each of the target gradations. 본 발명의 표시 장치는 대상 프레임을 구성하는 계조들로 발광하는 유기 발광 다이오드들; 상기 유기 발광 다이오드들의 일전극에 인가되는 전원 전압을 공급하는 전원 전압 공급부; 상기 계조들 중 최고 계조를 기준으로 내림차순으로 대상 계조들을 추출하고, 상기 대상 계조들 각각의 개수에 기초하여 상기 전원 전압의 크기를 결정하는 전원 전압 결정부를 포함한다.
