1. A display panel, comprising:
a base substrate;
a gate metal layer and a source/drain metal layer sequentially laminated on a side of the base substrate along a direction away from the base substrate; and
an inorganic insulating layer and an organic planarization layer sequentially laminated between the gate metal layer and the source/drain metal layer along the direction away from the base substrate;
wherein an orthographic projection of the gate metal layer on the base substrate and an orthographic projection of the source/drain metal layer on the base substrate have an overlapped portion, and an orthographic projection of the organic planarization layer on the substrate overlaps the overlapped portion; and
the base substrate is provided with a display region and a non-display region surrounding the display region; wherein the organic planarization layer is disposed in the display region and is not disposed in the non-display region; and each of the source/drain metal layer, the gate metal layer and the inorganic insulating layer is disposed in both the display region and the non-display region.
