1. A display device comprising:
a plurality of unit pixels comprising a main pixel and a redundancy pixel which emit a same color, the main pixel comprising a red main pixel, a green main pixel, and a blue main pixel, and the redundancy pixel comprising a red redundancy pixel, a green redundancy pixel, and a blue redundancy pixel; and
a gate driver integrated in each of the plurality of unit pixels, the gate driver comprising a plurality of stages and the gate driver disposed between two of the red main pixel, the green main pixel, and the blue main pixel or between two of the red redundancy pixel, the green redundancy pixel, and the blue redundancy pixel,
wherein each of the plurality of stages comprises a scan driving circuit for outputting a first scan signal and a second scan signal, and an emission driving circuit for outputting an emission control signal,
wherein an output timing of the first scan signal supplied to the main pixel is same as an output timing of the first scan signal supplied to the redundancy pixel, and
wherein an output timing of the second scan signal supplied to the main pixel is different from an output timing of the second scan signal supplied to the redundancy pixel.
