Title: Display device and method for driving a display device

Abstract: A display device driver constructed of scanning selection switches corresponding to a plurality of scanning wiring lines, a non-selection switch which brings the scanning wiring line into a non-selected state, a feedback switch which detects a scanning electrode potential and a negative feedback amplifier which sets the scanning electrode potential to a predetermined potential every electrode based on the scanning electrode potential detected by the feedback switch, and a time constant formed of a combined capacitance of a capacitance of the feedback switch and a wiring line capacitance and a feedback switch resistance is set to be smaller than that of a display panel capacitance and a scanning selection switch resistance.
