Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gamma reference voltage generator which reduces a circuit cost, reduces electric power consumption and reduces the area occupying in a printed circuit board and a liquid crystal display using the same. SOLUTION: The gamma reference voltage generator includes a voltage dividing means for providing a plurality of voltage dividing signals and a plurality of voltage followers for receiving one of the plurality of the voltage dividing signals and outputting the gamma reference voltages, respectively. The liquid crystal display utilizing such gamma reference voltage generator includes the voltage dividing means for providing the plurality of the voltage dividing signals and a plurality of data driving integrated circuits wherein each data driving integrated circuit receives one of the plurality of the voltage dividing signals and includes the plurality of the voltage followers respectively outputting the gamma reference voltages.
