Mutual capacitive touch panel

Abstract

Disclosed herein is a mutual capacitive touch panel, including: a first transparent substrate; a first bar-shaped transparent electrode formed on the first transparent substrate and divided in a length direction; first wiring whose one set of ends are connected to the first bar-shaped transparent electrode and whose the other set of ends are arranged on one side of the first transparent substrate; a second transparent substrate; a second bar-shaped transparent electrode formed on the second transparent substrate and divided in a length direction; second wiring whose one set of ends are connected to the second bar-shaped transparent electrode and whose the other set of ends are arranged on one side of the second transparent substrate; and an adhesive layer disposed between the first bar-shaped transparent electrode and the second bar-shaped transparent electrode such that the first bar-shaped transparent electrode and the second bar-shaped transparent electrode face each other. The mutual capacitive touch panel is advantageous in that, since transparent electrodes are divided, low resistance can be realized even when the transparent electrodes are made of a conductive polymer, thus keeping up with the trend of manufacturing large touch panels.
