## Abstract

A method of manufacturing touch control panel structure includes providing a substrate. Then a transparent electrode layer is formed on a display area of the substrate. Next, a metal wiring layer is formed on a peripheral area of the substrate. The peripheral area surrounds the display area. Finally, the substrate is cut to form a touch control panel structure. A cutting line goes through the metal wiring layer, and an edge of the metal wiring layer is flushed against an edge of the substrate.
