Abstract
A display device includes a display panel including touch electrodes, and a touch driving circuit including a driving signal output unit that outputs a touch driving signal supplied to the touch electrodes and a touch control unit that controls the driving signal output unit. The touch control unit sets the touch driving signal to swing between a first voltage and a second voltage higher than the first voltage, set the touch driving signal to rise to a third voltage higher than the second voltage and then lower from the third voltage to the second voltage, during a rising edge period, and set the touch driving signal to fall to a fourth voltage lower than the first voltage and then rise from the fourth voltage to the first voltage, during a falling edge period.
