Abstract
Provided is a capacitance type touch panel, including: X electrodes which are arranged in parallel in a first direction; Y electrodes which are arranged in parallel in a second direction; and extraction wirings which are connected to one end portions of the Y electrodes, respectively. Each of the extraction wirings is connected to a terminal corresponding to the each of the extraction wirings, 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 the another end portion of the first Y electrode and the another end portion of the second Y electrode.
