Abstract
A method of forming an array substrate, the array substrate and a display device are provided. The method of forming the array substrate includes: in a case that a display unit is formed on one of two opposite surfaces of a base substrate and a driving circuit is formed on the other of the two opposite surfaces of the base substrate, performing a roughening treatment on edge regions of the two opposite surfaces of the base substrate and a side surface of the base substrate connecting the edge regions of the two opposite surfaces, to form a roughened region; and forming, at the roughened region, a metal wiring connecting a signal input terminal of the display unit and a signal output terminal of the driving circuit.
