A display device comprising a display panel having touch sensors and gate lines, a touch sensor driver configured to supply a touch driving signal to the touch sensors of the display panel during a touch sensor driving period, a gate driver configured to supply a gate pulse synchronized with a data voltage of an input image to the gate lines of the display panel during a display driving period and supply an alternating current (AC) signal having a same phase as the touch driving signal to the gate lines during the touch sensor driving period, and a modulator configured to supply the AC signal having the same phase as the touch driving signal to the gate driver during the touch sensor driving period.

Display device

Disclosed are a gate driving unit capable of having reduced design area and power consumption by reducing an off-time of a gate signal, and an LCD device having the same. The gate driving unit includes N stage circuit units driven by receiving a start signal and first to fourth clock signals from the outside, wherein each stage circuit unit is configured to output gate signals by at least one of the first to fourth clock signals, and to receive gate signals output from an (N+3)th stage circuit unit to thus use as reset signals.
