PURPOSE: A display device and a source line driving method thereof are provided to reduce the number of bus lines by selecting gamma voltages corresponding to a single color among gamma voltages corresponding to a plurality of colors and transferring the voltages to a common bus line. CONSTITUTION: A plurality of gamma generating parts generates gamma voltages corresponding to each color, respectively. A first gamma generating part(20) generates first gamma voltages corresponding to the red. A second gamma generating part(21) generates second gamma voltages corresponding to the green. A third gamma generating unit(22) generates third gamma voltages corresponding to the blue. A selection part(24) selects gamma voltages corresponding to a single color among gamma voltages which are generated from a plurality of gamma generating parts to a common line. A decoding part(26) decodes gamma voltages outputted to the common line, respectively. An output part buffers the decoded signals, respectively and outputs the signals to source line driving signals.
