Display device

A display device having an electrostatic capacity touch panel for detecting touch position coordinates in a display region by an electrostatic capacity coupling method, wherein the electrostatic capacity touch panel comprises:

• a plurality of X electrodes which extend in a first direction in a first plane, wherein each of the X electrodes is formed by thin line parts and pad parts which are alternately arranged in the first direction;
• a plurality of Y electrodes which extend in a second direction, which intersects the first direction, in a second plane, wherein each of the Y electrodes is formed by thin line parts and pad parts which are alternately arranged in the second direction;
• a plurality of Z electrodes which are in a third plane, and are at an electrically floating state with respect to each other;
• a first insulating layer which is located between the first plane and the second plane;
• and
• a second insulating layer which is located between the second plane and the third plane;
• wherein the first, second and third planes are planes different from one another;
• wherein each of the plurality of X electrodes and each of the plurality of Y electrodes intersect each other via the first insulating layer;
• wherein the pad part of the each of the plurality of X electrodes and the pad part of the each of the plurality of Y electrodes are disposed without overlapping each other in plan view;
• wherein each of the plurality of Z electrodes overlaps both an X electrode and a Y electrode which are adjacent to each other in plan view;
• and
• wherein a difference between a combined capacity between the X electrode and the Y electrode during a touch operation of the electrostatic capacity touch panel, and during a no touch operation of the electrostatic capacity touch panel, corresponds to a difference between a serially connected capacity of:
• a capacity between the Z electrode and the X electrode, and a capacity between the Z electrode and the Y electrode.
