A touch screen panel includes a substrate having first and second surfaces opposite to each other, a plurality of first sensing electrodes formed on the first surface of the substrate and connected in a first direction, a plurality of second sensing electrodes arranged between the first sensing electrodes and connected in a second direction intersecting the first direction, first connecting patterns connecting the first sensing electrodes in the first direction, a plurality of third sensing electrodes formed on the second surface of the substrate and overlapping the first sensing electrodes, a plurality of fourth sensing electrodes arranged between the third sensing electrodes and overlapping the second sensing electrodes, and second connecting patterns connecting the fourth sensing electrodes in the second direction. The sensing electrodes of the first surface and the sensing electrodes of the second surface overlap each other and are electrically connected to each other through vertical connecting units.
