1. A display panel, including a display region and a non-display region, where the non-display region is on at least one side of the display region, comprising:
a substrate;
a light-emitting unit layer on a side of the substrate, wherein the light-emitting unit layer includes pixel units, at the display region, arranged in an array; and
a light-blocking layer on a side of the light-emitting unit layer away from the substrate, wherein the light-blocking layer includes first openings and second openings, wherein:
the first openings are at the display region; and along a direction perpendicular to the substrate, the pixel units correspond to the first openings; and
the second openings are at least on a side of the non-display region adjacent to the display region; and along a first direction, opening areas of the second openings gradually increase, wherein the first direction is a direction parallel to the substrate and parallel to a plane that separates the non-display region from the display region.
