Abstract: A pixel array including a plurality of pixel units is provided. Each of the pixel unit includes at least a first color subpixel, a second color subpixel and a Nth color subpixel, wherein N is an integer and N≥3. The first color subpixel includes a first stacked light-emitting layer, the second color subpixel includes a second stacked light-emitting layer, and the Nth color subpixel includes a Nth stacked light-emitting layer. The first stacked light-emitting layer, the second stacked light-emitting layer, and the third stacked light-emitting layer each include a main light-emitting layer and an auxiliary light-emitting layer. The main light-emitting layer of the first color subpixel and the auxiliary light-emitting layer of the second color subpixel are the same material layer. The main light-emitting layer of the Nth color subpixel and the auxiliary light-emitting layer of the first color subpixel are the same material layer.
