Display apparatus and driving method thereof

摘要

Display is effected by applying a DC voltage to electrodes 4 and 5 to change distribution states of migration particles 3 a and 3 b and by applying an AC voltage to electrodes 4 and 5 to move the migration particles 3 a and 3 b in a strong electric field created in a closed container depending on a relationship of different relative dielectric constants between the migration particles 3 a and 3 b and a dispersion medium 2 . A plurality of display states is switchable without increasing the number of electrodes.
