A display panel, comprising:
- a driver circuit layer having a first surface and a second surface disposed opposite to the first surface;
- a metal layer disposed on the first surface and provided with gaps;
- an insulating layer disposed on one surface of the metal layer away from the driver circuit layer and embedded into the gaps;
- a plastic layer disposed on one surface of the insulating layer away from the driver circuit layer;
- a sealing layer covering a surface of the plastic layer away from the driver circuit layer;
- a retaining wall extending from the first surface to the sealing layer and disposed on a middle position of the driver circuit layer, wherein the retaining wall is disposed in one of the gaps;
- and
- an insulating film disposed between the plastic layer and the sealing layer and on one side of the retaining wall.
