Abstract
A display medium includes a pair of substrates, an electrophoretic medium, and a partitioning medium. The pair of substrates is disposed in spaced-apart relation and substantially parallel to each other. The electrophoretic medium is disposed between the pair of substrates and contains charged particles. An electric field generated between the pair of substrates causes the charged particles contained in the electrophoretic medium to migrate for switching a display state. The partitioning medium has fluidity and is phase-separated from the electrophoretic medium at least at room temperature. The partitioning medium is in a phase-separated state phase-separated from the electrophoretic medium. The partitioning medium is disposed between the pair of substrates as a partition to partition the electrophoretic medium.
