Abstract
Disclosed is a data driver including a zero compensation resistor connected in series with a phase compensation capacitor between an output node of an input differential amplification stage and an output node of a succeeding amplification stage, and a control circuit that controls to switch a resistance value of the zero compensation resistor. The control circuit switches the resistance value of the zero compensation resistor to a first resistance value or a second resistance value larger than the first resistance value in response to turning off or on of an output switch that controls connection between the output terminal of an amplifying circuit and a data line.
