Touch screen panel integrated display device and display panel
The present invention relates to touch screen panel integrated display panel and display device. The touch screen panel integrated display panel comprises: a common electrode to which a common voltage is applied in a display mode and a touch driving signal is applied in a touch mode; a gate line that transfers a scan signal to a pixel row; and a gate driving integrated circuit that is connected to the gate line and outputs the scan signal to the gate line, wherein the gate driving integrated circuit includes a pull-up transistor and a pull-down transistor for outputting the scan signal to the gate line in the display mode, and additionally includes a touch mode transistor for outputting the touch driving signal applied to the common electrode or a signal corresponding to the touch driving signal to the gate line in the touch mode.
