1. A stretchable pixel array substrate, comprising:
a base, having a plurality of first regions and a second region, wherein the second region is located among the plurality of first regions;
a plurality of pixel structures, respectively disposed on the plurality of first regions of the base; and
a wiring, disposed on the second region of the base and electrically connected to the plurality of pixel structures, wherein the wiring comprises a plurality of curved segments serially connected to each other, each of the plurality of curved segments has a first curved portion, a second curved portion, and a third curved portion, the second curved portion is connected between the first curved portion and the third curved portion, a curved direction of the first curved portion is different from a curved direction of the third curved portion, the third curved portion of each of the plurality of curved segments is connected to the first curved portion of the next curved segment of the plurality of curved segments, and the plurality of curved segments of the wiring comprises:
a first curved segment, wherein the first curved segment is a curved segment of the wiring closest to one of the plurality of first regions; and
a second curved segment, wherein one of the plurality of pixel structures is disposed on the one of the plurality of first regions, and the first curved segment is disposed between the one of the plurality of pixel structures and the second curved segment;
wherein a distance A exists between the first curved portion of the first curved segment and the second curved portion of the first curved segment in a first direction, a distance B exists between the first curved portion of the second curved segment and the second curved portion of the second curved segment in the first direction, and A>B.
