Claim Text:
1. A gamma reference voltage generating circuit comprising: a first voltage follower configured to receive a first reference voltage generated by a first digital-to-analog converter and output a first gamma reference voltage; an nth voltage follower configured to receive a second reference voltage generated by a second digital-to-analog converter and output an nth gamma reference voltage, where n is a natural number equal to or greater than 3; a resistor string configured to generate divided voltages based on the first gamma reference voltage and the nth gamma reference voltage, the resistor string generating the divided voltages by dividing a voltage difference between the first gamma reference voltage and the nth gamma reference voltage; and second to (n−1)th voltage followers configured to receive the divided voltages and output second to (n−1)th gamma reference voltages generated based on the divided voltages.
