Disclosed is a touch screen device that may include first and second substrates; a plurality of first electrode lines and a plurality of second electrode lines on the first substrate that cross each other to define a plurality of touch sensors, each touch sensor including first and second electrodes, and an elastic resistor, with a gap space between the second electrode and the elastic resistor; and a touch driver that is electrically connected to at least one of the plurality of first electrode lines and the plurality of second electrode lines, and that determines a two-dimensional or three-dimensional touch information depending on an amount of force that is applied to the touch screen device.
