Abstract A display device according to an embodiment comprises a display area which includes a plurality of pixels, and a peripheral area which is located around the display area and includes a driving signal transmission line, wherein each of the plurality of pixels comprises a transistor, a driving voltage line connected to the transistor and the driving signal transmission line, and a light-emitting part connected to the transistor. The plurality of pixels includes a first pixel and a second pixel which are spaced apart from each other to have different intervals from the driving signal transmission line. The concentration of impurities doped on the semiconductor layer of the transistor of the first pixel may be different from the concentration of impurities doped on the semiconductor layer of the transistor of the second pixel. Therefore, the display device can uniformly maintain the brightness of the light-emitting parts regardless of the position of the pixels. 실시예에 따른 표시 장치는 복수의 화소를 포함하는 표시 영역, 그리고 상기 표시 영역의 주변에 위치하고, 구동 신호 전달선을 포함하는 주변 영역을 포함하고, 상기 복수의 화소 각각은 트랜지스터, 상기 트랜지스터와 상기 구동 신호 전달선에 연결된 구동 전압선, 상기 트랜지스터에 연결된 발광부를 포함하고, 상기 복수의 화소는 상기 구동 신호 전달선으로부터 서로 다른 간격을 가지도록 이격되어 있는 제1 화소와 제2 화소를 포함하고, 상기 제1 화소의 상기 트랜지스터의 반도체층에 도핑된 불순물의 농도는 상기 제2 화소의 상기 트랜지스터의 반도체층에 도핑된 불순물의 농도와 다를 수 있다.
