Abstract: A method for manufacturing an edge-chamfered OGS touch panel is disclosed. Before a pre-prepared glass substrate is subjected to etching, an upper lamination film and a lower lamination film are respectively laminated on upper and lower surfaces of the glass substrate. The upper lamination film is smaller than the lower lamination film so that when the upper lamination film is laminated on the surface of the glass substrate, an edge exposure zone is preserved on the glass substrate at a location adjacent to a substrate edge. When the substrate edge of the glass substrate is subjected to etching, a chamfered edge is formed on the touch operation surface of the glass substrate that is adjacent to the substrate edge.
