1. A display panel, comprising:
a flexible substrate; and
a driving circuit layer and a light-emitting functional layer disposed on the flexible substrate;
wherein the flexible substrate comprises a first flexible substrate, a second flexible substrate, and an inorganic layer between the first flexible substrate and the second flexible substrate, the first flexible substrate is disposed on one side of the second flexible substrate away from the driving circuit layer, and the first flexible substrate is provided with a first through-hole corresponding to a lighting path of an electronic component, wherein a ring-shaped opening is formed in the inorganic layer, and an outer boundary of the ring-shaped opening coincides with a boundary of the first through hole, wherein the ring-shaped opening includes a portion of the inorganic layer within the ring-shaped opening.
