Abstract: The present disclosure relates to a display device and a position input system including the same. According to an embodiment of the disclosure, a display device includes a display panel, a display unit disposed on the display panel and comprising a plurality of emission areas, a plurality of touch electrodes disposed between the plurality of emission areas and configured to sense a touch input, and a plurality of position code patterns. Each of the plurality of position code patterns is disposed to overlap a corresponding touch electrode in a position code pattern forming region. A width in a horizontal direction of the touch electrodes formed in the position code pattern forming regions is greater than a width in the horizontal direction of the position code patterns overlapping on a front surface thereof. The horizontal direction is parallel to an extending plane of the display panel.
