1. A display panel, comprising:
a base substrate, wherein the base substrate comprises a first display region and a second display region located at least on a side of the first display region, the second display region comprises a plurality of light transmitting regions and a plurality of pixel cell regions, and at least one pixel cell region in the plurality of pixel cell regions comprises a plurality of sub-pixels;
a pixel driving circuit layer located on a side of the base substrate and at least in the second display region, wherein the pixel driving circuit layer comprises a pixel driving circuit and a pixel driving circuit trace electrically connected to the pixel driving circuit, the pixel driving circuit trace includes a plurality of first traces extending in a first direction and a plurality of second traces extending in a second direction intersecting the first direction, and a first slit is between two adjacent first traces and a second slit is between two adjacent second traces;
a plurality of light-emitting elements located in the second display region and on a side of the pixel driving circuit layer away from the base substrate, and a light-emitting element comprises an anode, a light-emitting layer, and a cathode stacked sequentially;
a touch function layer located on a side of the plurality of light emitting elements away from the base substrate and at least in the second display region, and at least one of an orthographic projection of the first slit on the base substrate and an orthographic projection of the second slit on the base substrate at least partially overlaps with an orthographic projection of the touch function layer on the base substrate; and
wherein a density of the sub-pixels in the first display region is greater than a density of the sub-pixels in the second display region.
