Claim 11:
12. A display device, comprising a display panel, wherein the display panel comprises:
a base substrate;
a first signal line, which is disposed on the base substrate, wherein the first signal line comprises a first sub signal line and a second sub signal line which are electrically connected to each other and are disposed in different layers, and the first sub signal line is disposed on one side of the second sub signal line facing toward the base substrate;
a planarization layer, which is disposed on one side of the first signal line facing away from the base substrate; and
a light-emitting element and a pixel spacer layer, which are disposed on one side of the planarization layer facing away from the base substrate; wherein
the planarization layer comprises a first opening, and along a direction perpendicular to the base substrate, the first sub signal line at least partially overlaps with the first opening;
wherein the second sub signal line comprises a first line segment and a second line segment, at least part of the first line segment extends to a display region of the display panel, and the first sub signal line is disposed in a non-display region of the display panel; and
a first end of the first sub signal line is connected to an end of the first line segment through a first via hole, the first via hole is disposes in the non-display region, and along the a projection direction is a direction perpendicular to the base substrate, the first via hole does not overlap with the first opening along the projection direction.
