The present disclosure relates to a display panel that includes: a separation layer disposed on a surface of a planarization layer facing away from a substrate in a transition area, and surrounds at least a part of an opening area of the substrate in a circumferential direction of the opening area, and a sidewall of the separation layer gradually is shrunk toward the substrate in a direction perpendicular to the substrate; and a barrier layer located in the transition area and at least covers a surface of the barrier layer facing away from the substrate. The barrier layer includes a material for blocking moisture and oxygen. The display layer covers the planarization layer and the barrier layer. The display layer includes a light-emitting layer, and the light-emitting layer is discontinuous at a sidewall position of the separation layer.
