Touch panel and display device

A touch panel, comprising:

• a detection region having a periphery shape that is non-rectangular, the detection region including a plurality of first electrodes that is disposed on a first main surface of a base having insulating properties and that extends in a first direction, and a plurality of second electrodes that is disposed on a second main surface of a side opposite the first main surface of the base and that extends in a second direction that crosses the first direction;
• and
• a wiring region that includes a plurality of first wirings disposed on the first main surface, a plurality of second wirings disposed on the second main surface, and a plurality of shield electrodes disposed on at least one of the first main surface and the second main surface, the wiring region surrounding a periphery of the detection region, wherein each of the plurality of first wirings is electrically connected to a first end of each of the plurality of first electrodes,
• each of the plurality of second wirings is electrically connected to a first end of each of the plurality of second electrodes,
• each of the plurality of shield electrodes is disposed facing each second end of at least one of the plurality of first electrodes and the plurality of second electrodes,
• the plurality of first wirings and the plurality of second wirings extend along the periphery of the detection region, and
• in an alternating arrangement portion in which the ends of the first electrodes and the ends of the second electrodes of the periphery of the detection region are alternately positioned, the first ends of the first electrodes are electrically connected to the first wirings and the second ends of the second electrodes face the shield electrodes, or the first ends of the second electrodes are electrically connected to the second wirings and the second ends of the first electrodes face the shield electrodes.
