ABSTRACT:
Each gamma characteristic adjusting unit in a gamma correcting circuit selects a reference voltage from basic voltages generated by a basic voltage generating circuit based on correction adjustment data and selects a reference-voltage output terminal from reference-voltage output terminal candidates of a gamma correction resistor circuit as a target from which the reference voltage is to be output. As double adjustments based on such two-stage selection are possible, the adjustment range for the gamma characteristic can be made wider.
