Abstract: An in-cell touch type display device includes a touch electrode that is in a touch panel and arranged at each touch block; a sensing line that is connected to the touch electrode, and transfers a touch driving signal from a source driving circuit during a touch sensing period; a gate-in panel (GIP) circuit that is in an array substrate, and outputs a gate signal to a gate line crossing and overlapping the sensing line, during a display period; and a load reduction circuit that outputs the touch driving signal to the gate line during the touch sensing period.
