description	The present invention relates to a display device capable of preventing deterioration or ignition of pixels due to overcurrent. More specifically, the display device according to an embodiment of the present invention includes: a display unit which includes pixels divided into a plurality of blocks; a power interface which outputs block currents; a current sensor which senses the block currents and outputs sensing values; and a block current control unit which detects a deteriorated block among the blocks and outputs a control voltage for controlling a block current supplied to the deteriorated block. The power interface may include a plurality of transistors including a first electrode connected to first power supply, a second electrode connected to a first power supply line, and a gate electrode connected to a control line. 본 발명은 표시 장치에 관한 것이다. 구체적으로, 본 발명의 일 실시예에 따른 표시 장치는 복수의 블록들로 구획되는 화소들을 포함하는 표시부, 블록 전류들을 출력하는 전원 인터페이스, 블록 전류들을 센싱하여 센싱값들을 출력하는 전류 센서 및 블록들 중 열화 블록을 검출하고, 열화 블록에 공급되는 블록 전류를 제어하기 위한 제어 전압을 출력하는 블록 전류 제어부를 포함하되, 전원 인터페이스는, 제1 전원과 연결되는 제1 전극과 제1 전원 공급 라인과 연결되는 제2 전극 및 제어 라인과 연결되는 게이트 전극을 포함하는 트랜지스터를 복수개 포함하는 것을 특징으로 한다.
