Claim 7:
8. The display substrate according to claim 1,
wherein the barrier structure comprises: a first barrier dam and a second barrier dam; the first barrier dam is farther from the plurality of pixel units relative to the second barrier dam, and a thickness of the first barrier dam is greater than a thickness of the second barrier dam; the first barrier dam comprises: a first planarization layer pattern, a second planarization layer pattern, and a second organic pattern which are arranged along a direction away from the base substrate; the second barrier dam comprises: a third planarization layer pattern and a third organic pattern which are arranged along a direction away from the base substrate; wherein the second planarization layer pattern and the third planarization layer pattern comprise a same material, and the first organic pattern, the second organic pattern and the third organic pattern comprise a same material,
or,
wherein the barrier structure comprises: a first barrier dam and a second barrier dam; the first barrier dam is farther from the plurality of pixel units relative to the second barrier dam, and a thickness of the first barrier dam is greater than a thickness of the second barrier dam; the first barrier dam comprises: a planarization layer pattern and a second organic pattern which are sequentially arranged in layers along a direction away from the base substrate; the second barrier dam comprises: a third organic pattern arranged on the base substrate, and wherein the first organic pattern, the second organic pattern and the third organic pattern comprise a same material.
