  • Patent number: 8681121
    Abstract: An electrostatic capacitive coupling type touch panel in which a period before wiring formed outside an input region is chipped or wire-broken due to deterioration of a mask pattern can be prolonged. The touch panel has an input region and plural wirings formed around the input region. The input region has plural X electrodes and plural Y electrodes crossing the X electrodes. The plural wirings are connected to corresponding electrodes of the plural X electrodes and Y electrodes. The plural wirings respectively have a conductive layer and a metal layer formed on the conductive layer. The conductive layer is formed to be wider than the metal layer. The plural wirings have a corner. Among the plural wirings, in the wiring provided in the farthest position from the input region, the corner of the metal layer is chamfered.
