A lower substrate including a first electrode and an upper substrate including a second electrode are opposed to each other. Partitioned spaces between the two substrates correspond to pixels, each including negatively charged black particles and positively charged white particles. In the lower substrate, a piezoelectric material is sandwiched between a third electrode and the first electrode, thereby forming a vibration-generating portion. In a display operation, a signal voltage corresponding to an image signal is applied between the first and second electrodes, and thus, the black particles and the white particles travel between the electrodes and adhere to the respective electrode surfaces to perform the display operation. Before rewriting the display, a sine wave voltage is applied between the first electrode and the third electrode to cause the vibration-generating portion to generate vibration. Aggregated particles are dissociated, and particles adhering to the electrode are detached, by the vibration.
