    Abstract: A touch-sensitive display device is provided. The touch-sensitive display device includes a display panel and a touch panel. The display panel includes first and second substrates facing each other. The display panel is configured to display images through the second substrate. The touch panel is disposed on the second substrate and is configured to detect a touch event. The touch panel includes sensing electrodes spaced apart from each other, a conductive layer, and a touch processor. The conductive layer is electrically separated from the sensing electrodes. The touch processor is configured to provide sensing signals to the sensing electrodes and to obtain touch coordinates to which the touch event is input based on delay values of the sensing signals.
