PROBLEM TO BE SOLVED: To provide a display device and a method for controlling a gate pulse modulation thereof, capable of modulating gate pulses which overlap each other without changing a configuration of a timing controller. SOLUTION: The display device includes a display panel in which data lines and gate lines cross each other, a timing controller which outputs a single FLK (gate pulse modulation control) signal and I-phase gate shift clocks (wherein I is an integer equal to or more than 2) sequentially delayed, an FLK frequency-dividing circuit which divides the single FLK signal to output J (wherein J is an integer equal to or more than 2 and smaller than I) FLK signals, a data driving circuit which converts digital video data into data voltages to supply the data voltages to the data lines, and a gate driving circuit which generates gate pulses by level-shifting voltages of the gate shift clocks, to modulate falling edge voltages of the gate pulses in response to the frequency divided FLK signals, and to sequentially supply the modulated gate pulses to the gate lines.
