Claim 15:
16. The display substrate according to claim 15, wherein the display substrate has a display region located in the encapsulation region, a thin film transistor, a light emitting device, and an encapsulation layer are sequentially arranged in the display region along a direction away from the base substrate, and the thin film transistor comprises a buffer layer, an active layer, a gate insulating layer, a gate pattern, an interlayer dielectric layer, a source-drain pattern, and a flattened layer that are sequentially arranged along a direction away from the base substrate;
the isolation dams are arranged in a same layer as at least one inorganic film layer of the thin film transistor, the inorganic film layer of the thin film transistor comprises the buffer layer, the gate insulating layer, and the interlayer dielectric layer; and
the organic layer is arranged in a same layer as the flattened layer.
