Abstract
A gamma voltage generation circuit includes a first resistor string that divides a high gamma reference voltage and low gamma reference voltage being input to output n (n: positive integer) gamma voltages; a plurality of buffers to transfer the n gamma voltages output from the first resistor string; and a second resistor string that divides a plurality of gamma voltages transferred from the plurality of buffers to output overall grayscale-specific gamma compensation voltages.
