The present invention relates to a display device in which an output level of a gate-off voltage is adjusted based on image signal information. According to the present invention, provided is the display device comprising: a gate drive unit which outputs a plurality of gate signals to a plurality of respective gate lines during first and second frames; and a display panel which displays a first image during the first frame, and displays a second image during the second frame having a duration longer than that of the first frame wherein each of the gate signals includes a high-level period having a first voltage level and a low-level period having a second voltage level lower than the first voltage level, and the second voltage level of the gate signals during the second frame is lower than the second voltage level of the gate signals during the first frame.
