Abstract: Disclosed is a display device that includes an array substrate that includes a display region and a first non-display region, and includes a signal line connected to a pixel in the display region; a first signal transfer line that is at the first non-display region and transfers a test signal, and a second signal transfer line that transfers a test enable signal; a connection pattern connected to the first signal transfer line; a test transistor that is connected between the signal line and the connection pattern, and is connected to the second signal transfer line; and an electrostatic induction element that includes a dummy device in the form of either a dummy pattern and/or a dummy test transistor, the dummy pattern including a dummy connection pattern connected to the first signal transfer line, the dummy test transistor connected to the second signal transfer line.

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.
