DATA DRIVING CIRCUIT AND DISPLAY DEVICE HAVING THE SAME

A data driving circuit of a display device is disclosed that includes a latch circuit to latch a data signal in response to a latch enable signal and to output a first signal, a level shifter to output a second signal obtained by changing a voltage level of the first signal, a digital-analog converter to output a third signal obtained by converting the second signal into an analog signal, an amplifier to output a fourth signal obtained by amplifying the third signal, a switch to output the fourth signal in a form of an image signal, in response to an output enable signal, and a signal generator to generate the latch enable signal and the output enable signal. The signal generator adjusts a start timing of the active duration of the latch enable signal, such that the active duration of the latch enable signal starts, after the inactive duration of the output enable signal starts.
