Claim 2:
3. The display device of claim 1, wherein the data driving circuit includes:
a shift register configured to convert the digital image data received in a serial form into image data in a parallel form in response to a control signal transferred from the timing controller and output the image data;
a latch circuit configured to transfer the image data in the parallel form, on a per-line basis, to be simultaneously supplied to a plurality of source driving integrated circuits;
a gamma circuit configured to generate a plurality of gamma reference voltages using the gamma driving power;
a digital-to-analog converter configured to convert the image data in the parallel form into the analog data voltage in response to the plurality of gamma reference voltages transferred from the gamma circuit; and
an output buffer configured to supply the analog data voltage to the plurality of data lines.
