1. A display panel having a display area and a non-display area located on at least one side of the display area, the display panel comprising:
a plurality of pixel driving circuits disposed in the display area and constituting a plurality of circuit columns arranged in a first direction; wherein a circuit column includes at least two pixel driving circuits arranged in a second direction, and the second direction and the first direction intersect;
a plurality of pads disposed in the non-display area and located on a side of the display area in the second direction;
a plurality of first data lines disposed in the display area, wherein a first data line extends in the second direction, and is coupled to the at least two pixel driving circuits in the circuit column;
at least one data lead; wherein a data lead in the at least one data lead is coupled to the first data line, and extends from the display area to the non-display area; the data lead is coupled to at least one pad in the plurality of pads; and
a plurality of first signal lines disposed in the display area; wherein a first signal line extends in the first direction, and includes a plurality of first line segments and at least one second line segment;
wherein the plurality of circuit columns constitute a plurality of circuit groups arranged in the first direction, and a circuit group includes at least one circuit column; the data lead is disposed between two adjacent circuit groups;
wherein the at least one data lead includes at least one second data lead, and a portion of a second data lead in the at least one second data lead located in the display area is arranged in a different layer from the first data line;
wherein the portion of the second data lead located in the display area is arranged in a same layer as the first line segments, and is disposed between two adjacent first line segments; and
two adjacent first line segments in the first direction are coupled through a second line segment in the at least one second line segment, and the second line segment is arranged in a different layer from the first line segments.
