Abstract
An electrophoretic display device includes a first display electrode and a second display electrode placed on a first substrate, and a second substrate placed in opposition to the first substrate through a bulkhead. Auxiliary display electrodes (projections), each of a projecting structure, are provided on the first display electrode and the second display electrode and along lines of portions where an absolute value of a horizontal component of an electric field generated over the first display electrode and the second display electrode, becomes minimum. A space formed by the first substrate, the second substrate, and the bulkhead is filled with a transparent insulating liquid, and colored electrophoretic particles are dispersed in the insulating liquid.
