1. A display panel, comprising a display area and a non-display area, wherein the non-display area comprises a bonding area and a bending area located between the display area and the bonding area;
the display panel further comprises:
a substrate;
a light-emitting layer arranged on a side of the substrate and located in the display area, wherein the light-emitting layer comprises a plurality of sub-pixels;
a first refractive layer arranged on a side of the light-emitting layer away from the substrate, wherein the first refractive layer comprises a plurality of openings defined in the display area, and the plurality of openings are arranged corresponding to the plurality of sub-pixels;
a second refractive layer covering a side of the first refractive layer away from the substrate and filling the openings, wherein a refractive index of the second refractive layer is greater than a refractive index of the first refractive layer, and the second refractive layer extends from the display area to the non-display area and covers the bending area; and
a first backplane and a second backplane, wherein the first backplane is located on a side of the substrate facing the second backplane and located in the display area, and the second backplane is located on a side of the substrate facing the first backplane and located in the bonding area.
