Abstract
A gamma reference voltage generating circuit including a first resistor string disposed between a first reference voltage node and a second reference voltage node, a first multiplexer connected to the first resistor string and determining a level of a first gamma reference voltage, a first amplifier connected to the first multiplexer and outputting the first gamma reference voltage, a first resistor connected between an output terminal of the first amplifier and a first previous gamma voltage output node, a second resistor connected between the output terminal of the first amplifier and a first next gamma voltage output node, a first compensating resistor connected between a second previous gamma voltage output node and the present gamma voltage output node, and a second compensating resistor connected between a second next gamma voltage output node and the present gamma voltage output node.
