Abstract
A method for manufacturing a touch panel includes following steps. A substrate is used and an upper surface thereof is formed with a plurality of lower electrode units. A periphery of each lower electrode unit is formed with a gluing frame, and a periphery of the substrate is formed with a sealing frame. A panel layer is used and a lower surface thereof is formed with a plurality of upper electrode units. By the gluing frame and the sealing frame, the substrate and the panel layer are combined together as a combined plate. The combined plate is etched by solution of hydrofluoric acid. One or more than one function film is attached to a surface above each electrode unit. A cutter is used for cutting the panel layer from an upper side thereof and to form a trench, and the substrate is pressed along the trench of the substrate for separating the substrate into a plurality of independent touch panels along the predetermined cutting line.
