Patent ID: 8741082

Claim:
A method of manufacturing an electrophoretic display device, the method comprising the steps of: forming a plurality of partition walls defining unipixel regions on a first substrate; filling an electrophoretic medium in the unipixel regions; forming an adhesive layer on a second substrate to bond the first substrate to the second substrate; forming (i) a plurality of adhesive portions for contact with the partition walls and (ii) a plurality of hardening portions for sealing the unipixel region filled with the electrophoretic medium by hardening a part of the adhesive layer; and bonding the first substrate and the second substrate to each other using a first mask, wherein the step of forming a plurality of partition walls comprises patterning a partition walls layer on the first substrate using the first mask, wherein the step of bonding the first substrate and the second substrate to each other comprises: arranging shielding parts of the first mask to cover the electrophoretic medium filled in the unipixel regions; and irradiating hardening light to the adhesive portions through opening parts of the first mask.
