Abstract

A display apparatus includes: a display panel including a plurality of pixels respectively connected to a plurality of gate lines; a gate driving circuit including a plurality of driving stages configured to apply gate signals to the gate lines; a voltage generator configured to output a gate-on voltage through a voltage output terminal thereof; and a signal controller configured to sense a variation in current of the voltage output terminal to output a back bias control voltage corresponding to the sensed current variation, wherein each of the driving stages comprises a plurality of oxide thin film transistors and at least one of the oxide thin film transistors is a four-terminal transistor in which a threshold voltage thereof is controlled by the back bias control voltage.
