Zusammenfassung:	Provided is a display device. The display device comprises a plurality of insulating layers, a light emitting element, and a pixel circuit electrically connected to the light emitting element. The pixel circuit comprises a first transistor. The first transistor comprises: a metal oxide semiconductor pattern comprising a source area, a drain area, and a channel area disposed between the source area and the drain area; a first gate disposed on the metal oxide semiconductor pattern and overlapping the channel area; and a metal oxide pattern disposed on the first gate. Therefore, an objective of the present invention is to provide the display device comprising an oxide transistor with a wider driving voltage range. 표시장치가 제공된다. 표시장치는 복수 개의 절연층들, 발광소자, 및 상기 발광소자에 전기적으로 연결된 화소회로를 포함한다. 상기 화소회로는 제1 트랜지스터를 포함한다. 상기 제1 트랜지스터는, 소스영역, 드레인영역, 및 상기 소스영역과 상기 드레인영역 사이에 배치된 채널영역을 포함하는 금속 산화물 반도체 패턴, 상기 금속 산화물 반도체 패턴 상에 배치되고, 상기 채널영역에 중첩하는 제1 게이트, 및 상기 제1 게이트 상에 배치된 금속 산화물 패턴을 포함한다.
