1. A display panel, comprising a display region and a non-display region, wherein the non-display region is located on a periphery of the display region;
wherein the display panel comprises:
a substrate;
a source line, wherein the source line is located in the non-display region; and
a signal line group, wherein the signal line group is located in the non-display region and is located on a same side of the substrate as the source line, the signal line group comprises a first signal line group, the first signal line group is located on a side of the source line along a first direction, wherein the first direction is parallel to a plane where the substrate is located; the first signal line group comprises a first signal line and a second signal line, and the first signal line and the second signal line transmit pulse signals which have opposite polarities;
wherein the first signal line comprises a first line segment and a second line segment which are coupled, and the second signal line comprises a third line segment and a fourth line segment which are coupled;
along the first direction, a distance between the first line segment and the source line is less than or equal to a distance between the third line segment and the source line; and
along the first direction, a distance between the second line segment and the source line is greater than or equal to a distance between the fourth line segment and the source line;
wherein the first signal line group further comprises a third signal line and a fourth signal line; the third signal line and the fourth signal line transmit pulse signals which have opposite polarities, and the third signal line and the first signal line transmit pulse signals which have a same polarity: the third signal line comprises a fifth line segment and a sixth line segment which are coupled, and the fourth signal line comprises a seventh line segment and an eighth line segment which are coupled;
wherein the display panel further satisfies one of the following:
along the first direction, the fifth line segment is located between the first line segment and the third line segment, and the seventh line segment is located on a side of the third line segment facing away from the first line segment; and along the first direction, the eighth line segment is located between the fourth line segment and the second line segment, and the sixth line segment is located on a side of the second line segment facing away from the fourth line segment; or
along the first direction, the seventh line segment is located on a side of the third line segment facing away from the first line segment, and the fifth line segment is located on a side of the seventh line segment facing away from the third line segment; and along the first direction, the sixth line segment is located on a side of the second line segment facing away from the fourth line segment, and the eighth line segment is located on a side of the sixth line segment facing away from the second line segment.
