Abstract: An electrophoretic display apparatus, electronic device, and driving method for an electrophoretic display apparatus are capable of significantly increasing the number of tones that can be expressed in a single frame period. The electrophoretic display apparatus divides at least part of a frame period into multiple subfield periods and controls the light transmission of an electro-optical layer by selecting, on a subfield period-by-subfield period basis, an on or off voltage as the driving voltage to apply between a pixel electrode and an opposing electrode to display multiple tones. A driving circuit of the electrophoretic display apparatus determines, in accordance with the tone to be displayed, the ratio between the application periods of the on and off voltages during the frame period, and the arrangement of the on and off voltages. The absolute values of the positive-polarity and negative-polarity voltages are different from each other.
