Abstract
A display substrate and a manufacturing method thereof are provided. The display substrate includes a base substrate, a first metal layer, a first insulating layer, a first electrode layer, a light-emitting material layer, a carbon-containing structural layer and a second electrode layer. The first metal layer includes an auxiliary electrode pattern; the first electrode layer and the light-emitting material layer include a via hole; the second electrode layer is electrically connected to the auxiliary electrode pattern through the carbon-containing structural layer. A distance between a surface, close to the base substrate, of the first metal layer and a surface, away from the base substrate, of the second electrode layer is respectively denoted by d1 and d2, and an average carbon-oxygen ratio of the carbon-containing structural layer is respectively denoted by c1 and c2, near a middle portion and near an edge of the via hole; and d1<d2 and c1>c2.
