ABSTRACT:
An electrophoretic display device including first and second substrates disposed with a predetermined spacing, a partition member disposed between the first and second substrates, a plurality of electrophoretic particles and an insulating liquid which are sealed up by the substrates and the partition member, and first and second electrodes disposed close to the insulating liquid, is produced through a production process comprising the following steps (A), (B), (C) and (D): (A) a step of filling the insulating liquid and the electrophoretic particles in a recess defined by the first substrate and the partition member, (B) a step of placing a first area of the second substrate to be in contact with the partition member in an uncured state and a second area of the second substrate to be in contact with the insulating liquid in a cured state, (C) a step of causing the first area of the second substrate to contact the partition member and the second area of the second substrate to contact the insulating liquid, and (D) a step of curing the first area of the second substrate contacting the partition member.
