Abstract:
1. An electrostatic capacitance type touch panel comprising: a substrate; a plurality of X electrodes which are formed over the substrate, the plurality of X electrodes extending in a second direction and being arranged in a first direction which intersects with the second direction; and a plurality of Y electrodes which are formed over the substrate, the plurality of Y electrodes extending in the first direction while intersecting with the X electrodes and being arranged in the second direction; a drive voltage being supplied to the plurality of Y electrodes from one side of the plurality of Y electrodes, wherein lead lines are connected to respective one-end portions of the Y electrodes, the Y electrodes placed inside an effective touch region, having extended inspection portions at a respective other-end outside the effective touch region where the lead lines are not connected, for inspecting electrical connections of the Y electrodes, respectively, the touch panel further comprises outside the effective touch region, a single continuous inspection electrode which is laminated to and faces respective ones of the extended inspection portions with an insulation film sandwiched therebetween, and a voltage for inspection is supplied to the inspection electrode and detected through the lead lines connected to the respective one-end portions of the Y electrodes during an inspection time and a voltage at the same phase as the drive voltage supplied to the Y electrodes is supplied to the inspection electrode during a usual operation time.
