Abstract
A display substrate and a display device are provided. The display substrate includes: a base substrate; a first conductive element, located on the base substrate; a first planarization layer, located on the first conductive element; a second conductive element, located on the first planarization layer, and connected to the first conductive element through a first via hole penetrating the first planarization layer; a second planarization layer, located on the second conductive element; the second conductive element is recessed at the first via hole, so that the second conductive element has a recessed portion and a peripheral portion located outside the recessed portion, the recessed portion has a bottom portion and a side portion, the bottom portion and the peripheral portion are connected by the side portion, and the side portion of the recessed portion has an uneven surface to be configured to make light irradiated thereon be diffusely reflected.
