Abstract: A touch screen panel includes a touch recognition area that recognizes a touch input and a non-recognition area that does not recognize the touch input. The touch recognition area includes first touch electrodes connected in a first direction and second touch electrodes connected in a second direction orthogonal to the first direction. The non-recognition area includes a driver that obtains coordinate information of the touch input by using the first and second touch electrodes and outer wires connecting the first and second touch electrodes and the driver.
