A touch screen panel includes a plurality of touch sensors. A touch sensor includes a first touch electrode unit that includes a plurality of first mesh pattern electrodes disposed to be spaced apart from each other in a sensing area where the first touch electrode unit and the second touch electrode unit intersect. The touch sensor also includes a second touch electrode unit that includes a plurality of second mesh pattern electrodes disposed between the plurality of first mesh pattern electrodes in the sensing area to be spaced apart from each other. The touch sensors also includes a at least one floating electrode disposed between the plurality of first mesh pattern electrodes and the plurality of second mesh pattern electrodes. The dielectric breakdown of the first touch electrode unit and the second touch electrode unit is suppressed to improve reliability of the touch screen panel.
