Abstract: An array substrate and a manufacturing method thereof, a display device and a manufacturing method thereof are provided, which belong to the technical field of display. The array substrate includes: an interposer substrate, a thin-film transistor disposed on one side of the interposer substrate, and a bonding connection line embedded in the other side of the interposer substrate. The bonding connection line is configured to be connected to a drive circuit. An interposer via hole is arranged on the interposer substrate. A conductive structure is arranged in the interposer via hole. The thin-film transistor is electrically connected to the bonding connection line by the conductive structure.
