Abstract
An electrostatic capacitive coupling type touch panel including an input region having four sides, a peripheral region around the input region, terminals formed in the peripheral region along a first side of the input region, wirings formed In the peripheral region along second, third and fourth sides of the input region, and the input region having X and Y electrodes crossing. The wirings are connected between corresponding X or Y electrodes and wiring terminals plurality of terminals. A dummy wiring, which is not connected to any of the X electrodes or Y electrodes, is provided outside the wiring formed in a farthest position from the input region, and the dummy wiring extends through the peripheral region along the second, third and fourth sides of the input region, and electrically connects to at least one dummy wiring terminal.
