Providing a touch panel that suppresses reflection of light and prevents a reduction in the visibility of an image even when strong outside light is incident thereon in an outdoor environment. The touch panel has a plurality of first electrodes juxtaposed in parallel to each other in a first direction and a plurality of second electrodes juxtaposed in parallel to each other in a second direction. The first electrodes are continuously formed, the second electrodes are discontinuously formed, and a connecting electrode that electrically connects each parts of each of the second electrodes at a discontinuous portion is arranged under each of the first electrodes through an interlayer insulating film. A contour line provided to the interlayer insulating film arranged on the connecting electrode is formed to be curved under each of the first electrodes or the second electrodes.
