| 摘要 |
A display medium includes a first substrate constituting a display surface, a second substrate disposed in opposition to the first substrate for forming a fluid chamber between the first and the second substrates, and a partition wall member for dividing the fluid chamber into a plurality of cells. The plurality of cells is filled with an electrophoretic medium wherein a charged particle dispersion including an organic solvent with dispersed charged particles is dissolved or dispersed in a dispersion medium. An image is displayed on the display surface by moving the charged particles based on the directions of electric fields generated between the first substrate and the second substrate. The manufacturing method includes a filling step for filling the plurality of cells with the charged particle dispersion before the partition wall member is covered with the first and second substrates, a subsequent injection step for injecting the dispersion medium for dissolving or dispersing the charged particle dispersion into the plurality cells.
