Abstract
A display backplane, a manufacturing method thereof, and a display device are provided. The display backplane includes a base substrate. A thin film transistor array layer, a protective layer, a planarization layer, and a light-emitting element are arranged on the base substrate. A first through hole is formed in the protective layer, and a second through hole is formed in the planarization layer. The first through hole and the second through hole are connected. A source electrode or a drain electrode is electrically connected to an anode via the first through hole and the second through hole. Each of the first through hole and the second through hole has a sidewall inclined relative to the base substrate.
