    Abstract: A manufacturing method of a display substrate, an array substrate and a display device are provided. The method includes forming a first wire, a first insulation layer, a first and second metal layer, and a photoresist layer; forming a photoresist retained pattern above the first wire; forming a second and first metal layer retained pattern under the photoresist retained pattern; forming a second insulation layer with a thickness less than or equal to a sum of thicknesses of the first and second metal layer; the second insulation layer forming a fracture region at a boundary between a part covering the first insulation layer and another part covering the second metal layer retained pattern; removing the first and second metal layer retained patterns by a wet etch process to expose the first insulation layer; and forming a contact hole exposing the first wire.

    Abstract: A light-emitting substrate includes: a substrate; and at least one coupling portion and at least one auxiliary cathode pattern disposed on the substrate. Each auxiliary cathode region is provided with a coupling portion and an auxiliary cathode pattern coupled to the coupling portion. The auxiliary cathode pattern includes at least one disconnection portion, and each disconnection portion includes first, second and third conductive pattern layers. An orthographic projection of an edge of the second conductive pattern layer on the substrate is located within orthographic projections of edges of the third and first conductive pattern layers on the substrate. A total perimeter of at least one orthographic projection, on the substrate, of at least one edge of at least one third conductive pattern layer in the at least one disconnection portion is greater than a perimeter of an orthographic projection of an edge of the auxiliary cathode region on the substrate.
