Abstract
An electrophoretic element includes: an electrophoretic particle; a porous layer formed of a fibrous structure containing a non-migrating particle having optical reflective characteristics different from those of the electrophoretic particle and having a plurality of pores; and a partition that is partially adjacent to the porous layer and defines a space for accommodating the electrophoretic particle. An area rate of the pores per unit area of the porous layer is small in an adjacent region where the partition is adjacent to the porous layer compared with in a non-adjacent region where the partition is not adjacent to the porous layer.
