Patent ID: 8508837

Claim:
A method of manufacturing an electrophoretic display device including a plurality of cells between opposed two substrates at least one of which is transparent, a display medium containing electrophoretic elements of at least one or more kind(s) being enclosed in each cell, and the display medium being configured to display predetermined information when a predetermined electric field is applied between the two substrates, the method of manufacturing an electrophoretic display device comprising: forming a partition wall on a one substrate with a predetermined pattern; forming an adhesive layer on the partition wall; filling each region as a cell, which has been partitioned by the partition wall, with a display medium, after having formed the adhesive layer; and adhering the other substrate onto the adhesive layer on the partition wall so as to enclose the display medium; wherein the forming of the adhesive layer is performed, with the use of a transfer film with a heat sealing agent formed thereon, by heat-transferring the heat sealing agent, and the adhering of the other substrate includes heating the heat sealing agent for again softening the heat sealing agent, which has been transferred as the adhesive layer, so as to obtain an adhesive force.
