Abstract:
1. An electrostatic capacitance-type input device comprising: a plurality of first electrodes, which detect an input position, extending in a first direction in an input area on a substrate; a plurality of second electrodes, which detect an input position, extending in a second direction intersecting with the first direction in the input area; a plurality of signal wirings that extend from one-side end portions of the first electrodes and one-side end portions of the second electrodes on the substrate; a test electrode that faces, and is capacitively coupled with, the other-side end portions of at least one of the first electrodes and the second electrodes through an insulating film on the substrate; a test wiring that is electrically connected to the test electrode; and a short-circuit testing unit that is electrically connected to the test wiring and the plurality of signal wirings, wherein the short-circuit testing unit measures capacitance values between the test wiring and the plurality of signal wirings and determines that the electrode out of the first electrodes and the second electrodes, which has a capacitance value equal to or less than a set value, and to which the signal wirings are electrically connected is short-circuited.
