A drive method for an electrophoretic display panel having one electrode as a common electrode and another electrode divided into a plurality of segment electrodes, the drive method having steps of: applying pulses that change between two different potential levels to the common electrode; applying pulses at one of the two potential levels to the segment electrode of a segment that changes display state to produce a potential difference to the pulse applied to the common electrode; applying pulses of the same phase and potential as the pulses applied to the common electrode to the segment electrode of a segment that holds the same display state; and inserting a high impedance state to the pulses applied to the common electrode and the pulses applied to the segment electrode of the segment that holds the same display state when the pulse potential changes.
