Abstract: A display device including a display panel including gate and data line that cross each other; a first control signal generation unit generating a source output enable signal and a first gate output enable signal in synchronization with a data enable signal modulated according to a spread frequency clock signal; a second control signal generation unit starting to count a number of clocks of a fixed-frequency clock signal based on a point of time at which a first state of the source output enable signal ends, and outputting a second gate output enable signal when the counted number of the clocks becomes equal to a reference value; and a gate driving unit controlling an outputting of a gate signal to the gate lines using the second gate output enable signal.
