Abstract:
1. An electrophoretic display device, comprising: a display unit which comprises a first substrate, a second substrate, and electrophoretic particles inserted between the first substrate and the second substrate; and a voltage applying unit which updates a display state of the display unit from a current image to a next image by applying prescribed voltage waveforms constituted with a stirring pulse, a compensation pulse, and a set pulse to the electrophoretic particles, wherein the voltage applying unit first sets the display state to a state where the electrophoretic particles are migrated to either the first substrate or the second substrate by the stirring pulse according to polarity of the electrophoretic particles, then applies a voltage for suppressing a residual direct current component that may be generated after applying the set pulse without causing a change in the display state by the compensation pulse, and updates the image to the next image by the set pulse.
