Patent ID: 7622148

Claim:
A method for manufacturing an electrophoretic display element including microcapsules, each of the microcapsules comprising a suspension comprising electrophoretic particles and a dispersion medium and a film formed of a coating material covering the suspension, the method comprising the steps of: providing a substrate having an electrode pattern; providing at least two concentrically arranged nozzles at a predetermined distance from the substrate; discharging the suspension from one of the concentrically arranged nozzles and discharging the coating material from another one of the concentrically arranged nozzles at a desired location of the electrode pattern on the substrate; and repeating the discharging step while the substrate is translated, thereby arranging the microcapsules on the substrate, wherein the discharging step comprises a step of adhering the coating material to the suspension arranged on the substrate so as to form a partition enclosing the suspension with the substrate and the coating material.
