Abstract
A data driving circuit of a display device includes a digital-analog converter which includes a gamma reference voltage generator to output gamma reference voltages in response to a first-group signal of a digital signal, and a voltage selector to output, as a gamma selection voltage, one of the gamma reference voltages in response to a second-group signal of the digital signal. The data driving circuit also includes a first amplifier to receive the gamma selection voltage and to output a first conversion voltage, a boosting circuit to convert the first conversion voltage into a second conversion voltage in response to the first-group signal of the digital signal, and a second amplifier to receive the second conversion voltage and to output an analog signal.
