1. A display device with a position inputting function comprising:

  • pixel electrodes linearly disposed;

    signal wirings configured to transmit signals supplied to the pixel electrode and disposed to sandwich the pixel electrodes;

    position detection electrodes each configured to form capacitors between the position detection electrodes and a position input member and to detect a position of input by the position input member;

    a position detection wiring connected to the position detection electrodes comprising at least;

    first wiring portions each sandwiched between the pixel electrodes and the signal wirings, wherein pairs of the first wiring portions are linearly disposed in an arrangement direction in which the pixel electrodes are disposed; and

    second wiring portions connecting ends of the first wiring portions adjacent to each other in the arrangement direction;

    conductive structural objects, at least sections of which are disposed in a layer in which the position detection wiring is disposed;

    bridging wirings disposed to cross the conductive structural objects and including sections connected to ends of the first wiring portions adjacent to each other in the arrangement direction or ends of the first wiring portions on a same side with respect to the arrangement direction through contact holes, wherein the ends of the first line portions adjacent to each other in the arrangement direction are not connected to the second line portions; and

    an insulating film disposed between the conductive structural objects and the bridging wirings, wherein the insulating film includes the contact holes.
