More Information
Summary:A display device with an improved characteristic of a transistor may comprise: a substrate; an organic light emitting element disposed on the substrate; a pixel circuit disposed between the substrate and the organic light emitting element, electrically connected to the organic light emitting element, and including first and second transistors; a first metal layer disposed between the substrate and the pixel circuit, overlapping with the first transistor, and supplied with a first voltage; and a second metal layer disposed between the substrate and the pixel circuit, overlapping with the second transistor, and supplied with a second voltage different from the first voltage. 표시 장치는 기판, 기판 상에 배치되는 유기 발광 소자, 기판과 유기 발광 소자 사이에 배치되고 유기 발광 소자와 전기적으로 연결되며 제1 트랜지스터 및 제2 트랜지스터를 포함하는 화소 회로, 기판과 화소 회로 사이에 배치되고 제1 트랜지스터와 중첩하며 제1 전압이 공급되는 제1 금속층, 그리고 기판과 화소 회로 사이에 배치되고 제2 트랜지스터와 중첩하며 제1 전압과 상이한 제2 전압이 공급되는 제2 금속층을 포함할 수 있다.
