1. A display panel, comprising:
a substrate;
a plurality of signal lines located on the substrate; and
a plurality of light-emitting elements, at least one of the plurality of light-emitting elements being located on a side of one of the plurality of signal lines facing away from the substrate,
wherein at least one of the plurality of light-emitting elements comprises a first electrode, a light-emitting layer and a second electrode that are stacked in sequence,
wherein in a direction perpendicular to the display panel, at least one of the plurality of signal lines comprises at least one overlapping portion that overlaps the light-emitting layer of one of the plurality of light-emitting elements, and
wherein an angle θ is formed between an extending direction of a part of the at least one overlapping portion and a pixel column direction in a display region of the display panel that satisfies: 0°<θ<90°, or an angle θ is formed between an extending direction of a tangent of a part of the at least one overlapping portion and a pixel column direction of a display region of the display panel that satisfies: 0°<θ<90°.
