Abstract

Provided in the present application are a display backplane and a fabrication method therefor, a display panel and a display device. The display backplane is divided into a display region and a non-display region which is arranged surrounding the display region, the non-display region comprising a fingerprint recognition region. The display backplane comprises: a base substrate; a thin film transistor array layer provided at one side of the base substrate; a capacitive electrode layer, which comprises a first electrode layer and a second electrode layer; a light-emitting element which is provided at the side of the thin film transistor array layer away from the base substrate; and a fingerprint recognition sensor, which is located in the fingerprint recognition region. Moreover, a drive electrode and a sensing electrode are respectively arranged on the same layer as the first electrode layer and the second electrode layer in the capacitive electrode layer.
