    Abstract: A method of manufacturing a display substrate includes: providing a base substrate; and forming a base insulating layer, a first conductive layer and an interlayer insulating layer that are sequentially stacked on top of one another at a side of the base substrate. The first conductive layer includes at least one break face, the base insulating layer includes a portion extending outward with respect to each of the at least one break face, and the break face and the corresponding portion extending outward constitute an unevenness portion having a stepped shape. The interlayer insulating layer covers at least the unevenness portion(s). Forming the interlayer insulating layer, includes: forming a first insulating sub-layer and a second insulating sub-layer that are sequentially stacked on top of one another; and forming one of the first insulating sub-layer and the second insulating sub-layer by curing a flowable insulating material.
