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.
Claims12
An electrophoretic element comprising:
- 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,
- wherein a thickness of the porous layer is small in the adjacent region compared with in the non-adjacent region.
A display device comprising:
- an electrophoretic element between a pair of substrates, one or both of the substrates being optically transparent,
- wherein the 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 on a side opposite to a display surface and defines a space for accommodating the electrophoretic particle,
- wherein a thickness of the porous layer is small in the adjacent region compared with in the non-adjacent region.
An electrophoretic element comprising:
- 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 defining a space for accommodating the electrophoretic particle,
- wherein a thickness of the porous layer is small in a first region where the partition exists compared with in a second region where the partition does not exist.
A display device comprising:
