Capacitance type touch panel and display device

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;
• and
• extraction wirings, which are connected to one end portions of the Y electrodes, respectively;
• and
• a detection conductive layer provided only 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 X electrodes are a first X electrode and a second X electrode, another end portion of the first X electrode and another end portion of the second X electrode have a coupling capacitance for AC-coupling at least one of the another end portion of the first X electrode and the another end portion of the second X 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 X electrode and the another end portion of the second X electrode;
• and
• the coupling capacitance comprises at least one of a capacitance formed between the another end portion of the first X electrode and the detection conductive layer and a capacitance formed between the another end portion of the second X electrode and the detection conductive layer.
