An object is to obtain a touch panel with improved sensitivity and enhanced display quality. A touch panel according to the present invention includes a touch screen including a plurality of first sensing lines formed of mesh-like conductors and arranged in parallel on a substrate, an insulating film formed over the substrate and the first sensing lines, a plurality of second sensing lines formed of mesh-like conductors and arranged in parallel on the insulating film, first dummy patterns arranged in areas opposed to areas between adjacent first sensing lines through the insulating film, and having a form as part of the mesh forms of the first sensing lines such that the adjacent first sensing lines form an apparently continuous mesh form in plan view, and second dummy patterns arranged in areas opposed to areas between adjacent second sensing lines through the insulating film, and having a form as part of the mesh forms of the second sensing lines such that the adjacent second sensing lines form an apparently continuous mesh form in plan view.
