Abstract
A display substrate and a display device are disclosed. The display substrate includes a base substrate; a plurality of pixel driving circuits; a first conductive layer; a first planarization layer; and a second conductive layer; the second conductive layer includes a first conductive portion, the first conductive portion includes a closed annular portion, which is separated from at least one conductive portion adjacent thereto, each light emitting element groups includes a first light emitting element, the first light emitting element includes a first anode, and an orthographic projection of the first anode overlaps with an orthographic projection of the closed annular portion; the plurality of conductive portions further include a second conductive portion adjacent to the first conductive portion, and an orthographic projection of the second conductive portion on the base substrate overlaps with the orthographic projection of the first anode on the base substrate.
