ABSTRACT:
An electrophotographic display includes a plurality of microcapsules each encapsulating therein an insulating liquid and a plurality of charged electrophoretic particles dispersed in the insulating liquid, a first substrate and a second substrate disposed opposite to each other so as to sandwich the plurality of microcapsules, and a plurality of electrodes capable of being supplied with a voltage. A voltage is applied between the plurality of electrodes to move the charged electrophoretic particles between a first internal wall portion of each microcapsule an external surface of which contacts the first substrate and a second internal wall portion of each microcapsule an external surface of which is substantially out of contact with both the first and second substrate, thereby to switch a display state.
