In this way, by adopting the arrangement of the plurality of LED display units 11 in an array, on the one hand, uniformity of the display effect of the display panel 1 can be improved, and on the other hand, arrangement of the wiring can be facilitated. With such a circuit design, the first sub-circuits 101a and the second sub-circuits 102a can be arranged along a shorter path, so that the total length of the first sub-circuits 101a and the second sub-circuits 102a is reduced, and the area occupied by the first sub-circuits 101a and the second sub-circuits 102a on the first surface 10a of the substrate 10 is reduced.

as an alternative embodiment, referring to fig. 3 and fig. 4 together, the LED display units 11 are arranged at intervals along the third direction a, the first circuit 101 is electrically connected to the LED display units 11 along the third direction a, the second circuit 102 includes a plurality of second sub-circuits 102a, each of the second sub-circuits 102a is electrically connected to each of the LED display units 11, and the third circuit 103 is electrically connected to each of the second sub-circuits 102a through the first through hole 100.
