Abstract
An electrophoresis display device includes electrophoresis display elements, corresponding to pixels of a display unit, each having a structure where a dispersion medium containing electrophoresis particles is interposed between a common electrode and a pixel electrode, a driving unit that applies a voltage between the common electrode and the pixel electrodes and drives the electrophoresis display elements, and a control unit that controls the driving unit. An image rewrite period, during which a rewrite display operation is performed on the electrophoresis display elements, includes a reset period and an image signal introducing period. During the image signal introducing period, the electrophoresis display elements are driven with a first data input pulse and a second data input pulse.
