1. A display panel, comprising:
a substrate;
N1 pixel driving circuit rows arranged along a first direction and located on a side of the substrate, wherein each of the pixel driving circuit rows comprises a plurality of pixel driving circuits arranged along a second direction, and the first direction intersects with the second direction;
a plurality of light-emitting elements, each of the plurality of light-emitting elements is electrically connected to one of the pixel driving circuits;
repair lines; and
repair driving circuits,
wherein along a direction perpendicular to a plane where the substrate is located, each of the repair lines at least partially overlaps with one of the repair driving circuits and also the pixel driving circuits;
wherein each of the repair driving circuits comprises a repair circuit and a first capacitor that are electrically connected, the repair circuit comprises at least two transistors and a second capacitor, and a capacitance of the first capacitor is greater than or equal to a capacitance of the second capacitor; and
wherein a number of first capacitors is N2, where both N1 and N2 are positive integers, and N2<2N1.
