Abstract
A display device includes a display panel; a touch sensor sensing a capacitance of a plurality of nodes corresponding to a plurality of touch points on the display panel, wherein plurality of nodes includes a center node and a peripheral node surrounding the center node; a touch controller sensing a touch by detecting a capacitance change of the center node and the peripheral node, wherein the capacitance change of the center node is greater than the peripheral node; and a conductive layer disposed over the touch sensor that increases the capacitance change of the peripheral node.
