1. A display panel, comprising a display region and a non-display region located on a side of the display region, wherein the display panel comprises:
a first substrate;
a driving circuit layer disposed on a side of the first substrate;
a light-emitting device layer disposed on a side of the driving circuit layer away from the first substrate;
a second substrate disposed opposite to the first substrate, wherein the driving circuit layer and the light-emitting device layer are located between the first substrate and the second substrate; and
a stress releasing layer disposed on a side of the second substrate close to the first substrate, wherein the stress releasing layer is disposed corresponding to the non-display region, and a concave section is disposed in the stress releasing layer;
wherein the stress releasing layer comprises a plurality of color resist blocks spaced apart; the concave section comprises a plurality of first grooves extending along a first direction, the plurality of first grooves are arranged along a second direction, the first direction intersects with the second direction; and the first grooves are defined between two adjacent color resist blocks arranged along the second direction; and
wherein a width of the first grooves is gradually expanded from a direction of the second substrate toward the first substrate.
