    摘要: 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.

    摘要: The present disclosure is in the field of display technologies, and provides an array substrate including an IGZO film layer, a gate layer, and a gate insulating layer. The gate layer is provided with broken lines at a position thereof overlapping the IGZO film layer to form a first gate line and a second gate line. The gate insulating layer is disposed between the IGZO film layer and the gate layer, and is provided with at least two through holes thereon, in which the first gate line is connected with the IGZO film layer through one of the through holes, and the second gate line is connected with the IGZO film layer through another through hole, thus, connecting the IGZO film layer in series into the gate layer.
