Abstract
A drive apparatus that drives a display medium that includes display and rear substrates, a disperse medium, and a particle group, includes a voltage application unit that applies first and second voltages to the display medium, in which, when a color of the particle group is displayed, the voltage application unit applies the first voltage higher than or equal to a threshold voltage necessary for the particle group to be detached from the display substrate or the rear substrate to a pixel where the particle group is moved between the substrates and applies the second voltage having a same polarity as the first voltage and is lower than the threshold voltage to the pixel where the particle group is moved between the substrates and to a pixel adjacent to the pixel where the particle group is moved between the substrates and the particle group of which is not moved.
