Abstract:
1. A capacitance type touch panel, comprising: a substrate; a plurality of X electrodes, which extends on the substrate in a second direction and is arranged in parallel in a first direction crossing the second direction; a plurality of Y electrodes, which extends on the substrate in the first direction so as to cross each of the X electrodes and is arranged in parallel in the second direction; extraction wirings, which are connected to one end portions of the Y electrodes, respectively; and a detection conductive layer only provided in a region of an end portion of at least one of the X electrodes and the Y electrodes and in a region extending outside an effective touch region of the touch panel; wherein: each of the extraction wirings is connected to a terminal corresponding to the each of the extraction wiring, the terminal being formed at one side of the substrate; provided that adjacent two of the Y electrodes are a first Y electrode and a second Y electrode, another end portion of the first Y electrode and another end portion of the second Y electrode have a coupling capacitance for AC-coupling at least one of the another end portion of the first Y electrode and the another end portion of the second Y electrode with the detection conductive layer; the detection conductive layer is formed, via an insulating film, in a layer different from the another end portion of the first Y electrode and the another end portion of the second Y electrode; and the coupling capacitance comprises at least one of a capacitance formed between the another end portion of the first Y electrode and the detection conductive layer and a capacitance formed between the another end portion of the second Y electrode and the detection conductive layer.
