1. A display panel, comprising: a base substrate, a light-emitting device located on the base substrate, a first flat layer located on a side of the light-emitting device away from the base substrate, and a black matrix located on a side of the first flat layer away from the base substrate, wherein the black matrix has a plurality of opening regions, color filters are arranged in corresponding opening regions, and the color filters are configured to filter external incident light; and
the first flat layer has a plurality of first concave faces arranged corresponding to the opening regions, the color filters fill the first concave faces, and the color filters further cover peripheral regions of the first concave faces;
wherein the display panel further comprises:
a second flat layer located on a side of each of the color filters away from the base substrate, and an optical adhesive layer located on a side of the second flat layer away from the base substrate;
wherein the second flat layer has a plurality of second concave faces arranged corresponding to the opening regions, and the optical adhesive layer fills the second concave faces; and a refractive index of the second flat layer is larger than a refractive index of the optical adhesive layer.
