Abstract

A differential amplifier according to an embodiment can be provided in a data driving device for driving pixels of a display panel. The differential amplifier can improve the slew rate of the differential amplifier by supplying dynamic current to an input circuit stage and/or a current mirror circuit stage of the differential amplifier through a boosting circuit stage.
