1. A display panel, comprising,
a substrate;
pixel circuit islands provided at a side of the substrate, wherein one of the pixel circuit islands comprises at least one pixel circuit;
light-emitting elements disposed at a side of the pixel circuit islands away from the substrate and respectively electrically connected to the at least one pixel circuit of the pixel circuit islands; and
light-blocking structures comprising at least one of a reflective structure or a light-absorbing structure,
wherein the light-blocking structures comprise first light-blocking structures, each of which is disposed on at least one sidewall of a pixel circuit island of the pixel circuit islands;
wherein the display panel further comprises a first insulating layer, and the first insulating layer comprises an opening comprising a first sidewall and a second sidewall which are opposite to each other;
wherein the pixel circuit islands comprise a first pixel circuit island and a second pixel circuit island, the sidewall of the first pixel circuit island comprises the first sidewall, and the sidewall of the second pixel circuit island comprises the second sidewall; and
wherein in a direction parallel to a plane in which the substrate is located, the first light-blocking structure on the first sidewall and the first light-blocking structure on the second sidewall comprise an interval therebetween.
