1. A display panel, comprising:
a first substrate;
at least one underlaying structure, arranged on the first substrate and in a non-display region of at least one side of a display region of the display panel; and
at least one supporting structure, arranged on one side, facing away from the first substrate, of the at least one underlaying structure,
wherein an orthographic projection of the supporting structure on the first substrate is within a range of an orthographic projection of the underlaying structure on the first substrate;
wherein the display panel further comprises: a color light filter layer arranged in the display region, and a plurality of spacers arranged on one side, facing away from the first substrate, of the color light filter layer;
wherein the plurality of spacers are divided into a plurality of main spacers and a plurality of sub-spacers; and
a sum of a height of the supporting structure and a thickness of the underlaying structure is greater than a sum of a height of one of the main spacers and a thickness of the color light filter layer;
wherein a contact density of the supporting structure in the first sub-regions is greater than 10,000 μm2/mm2;
a contact density of the supporting structure in the second sub-regions is greater than 5,000 μm2/mm2; and
a compression amount of the supporting structure is within a range of 0.1 to 0.3 μm;
wherein the supporting structure comprises: strip-shaped spacers;
wherein gaps between the plurality of pixel units in the second direction are first gaps; in each of the second sub-regions, the strip-shaped spacers extend in the second direction and are arranged in an array; and orthographic projections of at least part of the strip-shaped spacers on a plane perpendicular to the second direction have overlapping regions with orthographic projections of the first gaps on the plane perpendicular to the second direction; wherein in each of the second sub-regions, a space between the strip-shaped spacer closest to the display region and the display region is greater than or equal to 0.5 mm; or,
in each of the second sub-regions, the strip-shaped spacers extend in the first direction; orthographic projections of the strip-shaped spacers arranged in a same second sub-region on a plane perpendicular to the second direction form a continuous figure; and in each of the second sub-regions, the farther from the display region, the longer the strip-shaped spacers in the first direction; wherein in each of the second sub-regions, a space between the strip-shaped spacer closest to the display region and the display region is greater than or equal to 1.5 mm.
