Abstract
A display substrate includes: a base substrate; a first conducting layer; a first insulating layer, where the first insulating layer is provided with a first opening; a second conducting layer, connected to the first conducting layer through the first opening, and including a first portion and a second portion, where the first portion is located within the first opening, and the second portion is located outside the first opening and located on the side of the first insulating layer facing away from the base substrate; and an inorganic protective layer including at least a first inorganic protective layer portion located between the second portion and the first insulating layer; in a direction perpendicular to the base substrate, the thickness h1 of the first inorganic protective layer portion and the thickness h2 of the second portion satisfy the following relationship: h2=K*h1, wherein 12≤K≤18.
