Abstract: A flexible assembly for a display device and the display device are provided. The flexible assembly includes a flexible substrate, and a first output pad, a second output pad, a third output pad and a fourth output pad that are arranged on the substrate. The first output pad, the second output pad, the third output pad and the fourth output pad are sequentially arranged along a first direction and are spaced apart from each other. A pitch is between each output pad and an adjacent output pad, and the pitch is a sum of a spacing distance between each output pad and the adjacent output pad and a width of the adjacent output pad in the first direction. The pitch between the first output pad and the adjacent second output pad is smaller than the pitch between the third output pad and the adjacent fourth output pad.
