Abstract The present invention provides a display device with an improved circuit characteristic comprising a thin film transistor. The display device comprises: a first interlayer insulating layer disposed on a substrate; a first semiconductor layer disposed on the first interlayer insulating layer and comprising an oxide semiconductor material; a first gate electrode disposed on the first semiconductor layer; a second interlayer insulating layer disposed on the first gate electrode; and a first electrode layer disposed on the second interlayer insulating layer and connected to the first semiconductor layer through a first contact hole penetrating the second interlayer insulating layer. The first semiconductor layer has an opening corresponding to the first contact hole, and the first electrode layer is in contact with an inner surface of the opening. 본 발명은 박막트랜지스터를 포함하는 회로의 특성이 향상된 디스플레이 장치를 위하여, 기판 상에 배치되는, 제1 층간절연층; 상기 제1 층간절연층 상에 배치되며 산화물 반도체 물질을 포함하는, 제1 반도체층; 상기 제1 반도체층 상부에 배치된, 제1 게이트전극; 상기 제1 게이트전극 상에 배치된, 제2 층간절연층; 및 상기 제2 층간절연층 상에 배치되고, 상기 제2 층간절연층을 관통하는 제1 콘택홀을 통해 상기 제1 반도체층과 접속하는, 제1 전극층;을 구비하고, 상기 제1 반도체층은 상기 제1 콘택홀에 대응하여 개구를 갖고, 상기 제1 전극층은 상기 개구의 내측면과 접촉하는 디스플레이 장치를 제공한다.
