1. A display panel, comprising:
a substrate;
light-emitting elements on a side of the substrate;
light-blocking structures on a side of the light-emitting elements away from the substrate,
wherein:
the light-emitting elements include first light-emitting elements and second light-emitting elements;
an area of an orthographic projection of a first light-emitting element on the substrate is S1, and an area of an orthographic projection of a second light-emitting element on the substrate is S2;
a light-blocking structure includes a first light-blocking structure and a second light-blocking structure;
an orthographic projection of the first light-blocking structure on the substrate at least partially surrounds a corresponding first light-emitting element and a distance from the first light-blocking structure to the corresponding first light-emitting element along a first direction is d1;
an orthographic projection of the second light-blocking structure on the substrate at least partially surrounds a corresponding second light-emitting element and a distance from the second light-blocking structure to the corresponding second light-emitting element along the first direction is d2, wherein the first direction is parallel to a plane where the display panel is located; and
|S1−S2|>0, and |d1−d21>0.
