Zusammenfassung:A display device and a driving method thereof are disclosed. A pixel circuit of the display device can be driven by a data sampling step and a light emitting step. In the data sampling step, a current flows in a first effective channel of a driving device, and in the light emitting step, a current flows in a second effective channel of the driving device. In an active pattern of the driving device, an effective channel through which current flows is designed as a long path and a short path to increase the channel length to reduce current and voltage fluctuations in devices due to process dispersion, and effective channel length in the light emitting step is reduced to increase on current. 표시장치와 그 구동 방법이 개시된다. 이 표시장치의 픽셀 회로는 데이터 샘플링 단계와 발광 단계로 구동될 수 있다. 상기 데이터 샘플링 단계에서 구동 소자의 제1 유효 채널에 전류가 흐르고, 상기 발광 단계에서 상기 구동 소자의 제2 유효 채널에 전류가 흐른다.
