Abstract: A display panel, a method of making the same, and a display device are disclosed. The method of making the display panel includes: forming a display motherboard including at least one metal trace, the at least one metal trace being connected to all uncut display panels on the display motherboard; cutting the display motherboard along a cutting line to form at least two display panels, where the at least one metal trace is exposed on at least one side of each of the at least two display panels; dripping a concentrated acid solution to an exposed position of the at least one metal trace to react for a preset time, thus corroding the at least one metal trace at the exposed position thus forming an insulating metal salt structure.
