Abstract
A pliable electrophoretic display device having a deformation-resistant memory characteristic is provided by covering a plurality of partitioning walls defining display sections containing a dispersion liquid with electrophoretic particle dispersed therein with an expandable ceiling sheet. Such a ceiling sheet is formed by applying a hardenable precursor liquid, which is immiscible with the dispersion liquid, over the partitioning walls containing the dispersion liquid and hardening the precursor liquid in situ by exposure to light, heat or by drying.
