Abstract
A display substrate is provided. The display substrate includes a first insulating layer disposed on a substrate, a second insulating layer disposed on the first insulating layer. In particular, the first insulating layer has a first opening and the second insulating layer has a second opening, wherein the first opening and the second opening are partially overlapped. Further, in a cross-sectional view, the first insulating layer corresponding to the first opening has two first bottom ends, and the second insulating layer corresponding to the second opening has two second bottom ends, a location of a first vertical central line between the two first bottom ends is different from a location of a second vertical central line between the two second bottom ends, and the first vertical central line and the second vertical central line are substantially parallel to a normal direction of the surface.
