Abstract
Provided is a display panel having a display region and a non-display region, and the display panel includes: a substrate; light-emitting elements disposed at a side of the substrate and located in the display region, each of light-emitting elements includes a light-emitting layer; and a light-shielding layer disposed at a side of the light-emitting elements facing away from the substrate, the light-shielding layer includes first apertures, and in a direction perpendicular to the substrate, each first aperture does not overlap with the light-emitting layer. In an embodiment, a distance between a first point on an edge of a first orthographic projection and a second point on an edge of a second orthographic projection is defined as a distance L, which satisfies where d denotes a distance between the light-emitting layer and the light-shielding layer, n denotes a refractive index of a functional film layer, θ denotes a visible angle and 0°<θ<90°.
