1. A display panel, wherein the display panel comprises a display region and a non-display region at least partially surrounding the display region, the non-display region is provided with a fan-out region,
the display panel comprises a substrate and a first power trace provided on the substrate, and the first power trace comprises a first portion provided in the fan-out region;
the first portion comprises a sheet-shaped trace proximal to an edge of the display panel and a first sub-portion extending from the sheet-shaped trace toward the display region; and
within a unit area, an area of an orthographic projection of the first sub-portion on the substrate is smaller than an area of an orthographic projection of the sheet-shaped trace on the substrate;
the first sub-portion comprises a plurality of strip-shaped traces spaced apart from one another;
the first portion further comprises a bus bar provided on one side of the plurality of strip-shaped traces distal to the sheet-shaped trace, and the plurality of strip-shaped traces each are connected to the bus bar; and
at least one strip-shaped trace of the plurality of strip-shaped traces comprises a first end portion adjacent to the bus bar, and an area of an orthographic projection of the first end portion on the bus bar becomes larger as the first end portion approaches the bus bar.
