主权项 1. A display device, comprising: a display panel in which data lines and gate lines intersect and pixels are disposed in a matrix form, the display panel including touch sensors; a touch driver circuit that drives the touch sensors; a data driver circuit that supplies a data signal to the data lines; a gate driving circuit that supplies gate pulses to the gate lines using a shift register; and a timing controller that supplies data of an input image to the data driver circuit and that controls operation timing of the data driver circuit and the gate driving circuit, wherein the timing controller generates a touch enable signal that defines a display time and a touch time, the touch enable signal at a low level voltage during the display time and a high level voltage during the touch time, and the shift register comprises a stage in which the touch enable signal is input, wherein the stage comprises: a Q node that controls a pull-up transistor; and a transistor comprising a drain directly connected to the Q node and a source directly connected to the touch enable signal, the high level voltage of the touch enable signal being applied to the source of the transistor during the touch time.
