1. A display panel, comprising:
a substrate, comprising a display area and a non-display area surrounding the display area;
a light-emitting device and an encapsulation layer which are disposed on the substrate, the light-emitting device being disposed in the display area; and
an auxiliary barrier disposed on the substrate, the auxiliary barrier being disposed in the non-display area;
wherein a height of the auxiliary barrier is greater than a distance between a side of the encapsulation layer away from the substrate and the substrate,
wherein the encapsulation layer comprises: a first inorganic encapsulation layer, an organic encapsulation layer and a second inorganic encapsulation layer which are laminated,
the display panel further comprising:
a barrier body disposed in the non-display area, wherein the barrier body is closer to the display area than the auxiliary barrier is, the first inorganic encapsulation layer and the second inorganic encapsulation layer cover the barrier body, and an orthographic projection of the organic encapsulation layer on the substrate and an orthographic projection of the barrier body on the substrate are not overlapped, wherein the barrier body is annular, and the barrier body is disposed around the display area, wherein two barrier bodies are provided, and the two barrier bodies are a first barrier body and a second barrier body respectively, wherein the first barrier body is closer to the display area than the second barrier body is, and a height of the second barrier body is greater than a height of the first barrier body, wherein the non-display area comprises: a diffusion area disposed between the second barrier body and the auxiliary barrier, and the encapsulation layer comprises an inorganic layer disposed in the diffusion area, wherein a thickness of the inorganic layer gradually decreases along a direction from the second barrier body to the auxiliary barrier.
