Abstract

A display panel and a display device are provided. The display panel includes a substrate, signal lines located on the substrate, and a plurality of light-emitting elements each located on a side of one of the signal lines facing away from the substrate. Each light-emitting element includes a first electrode, a light-emitting layer, and a second electrode that are stacked sequentially. Each signal line includes at least one overlapping portion overlapping the light-emitting layer of one of the light-emitting elements in a direction perpendicular to the display panel. An angle θ between an extending direction of a part of the at least one overlapping portion and a pixel column direction in a display region that satisfies: 0°<θ<90°, or an angle θ between an extending direction of a tangent of a part of the at least one overlapping portion and a pixel column direction in a display area that satisfies: 0°<θ<90°.
