1. A display panel, comprising a first substrate, wherein the first substrate comprises a plurality of sub-pixel areas arranged in an array, and at least one of the plurality of sub-pixel areas comprises:
a main bonding pad and a backup bonding pad which are disposed on the first substrate; and
a micro light-emitting diode electrically connected to the main bonding pad or the backup bonding pad,
wherein the main bonding pad and the backup bonding pad are disposed in a first symmetric manner with respect to a first symmetric reference object;
the at least one of the plurality of sub-pixel areas comprises a color resist structure, and the color resist structure is disposed in a third symmetric manner with respect to a third symmetric reference object; the third symmetric manner is the same as the first symmetric manner; and
a distance between a vertical projection of the third symmetric reference object on the first substrate and the vertical projection of the first symmetric reference object on the first substrate is S2, wherein S2≤10 μm.
