Abstract
An electrophoretic device includes: in an insulating liquid, a plurality of electrophoretic particles; and a porous layer formed of a fibrous structure, the fibrous structure including a plurality of non-migrating particles. The fibrous structure is configured of superposed fibers extending in an identical direction or different directions, and includes a cross-linking section in which the fibers are linked to each other in part or all of contact points between the fibers.
Claims18
An electrophoretic device comprising:
- in an insulating liquid:
- a plurality of electrophoretic particles;
- and
- a porous layer formed of a plurality of fibrous structures, the plurality of fibrous structures comprising a plurality of non-migrating particles,
- wherein each of the plurality of fibrous structures comprises two or more superposed fibers extending in an identical direction or different directions, and wherein the two or more superposed fibers are adhered to each other at one or more points of contact between the two or more superposed fibers to form one of the plurality of fibrous structures.
A method of manufacturing an electrophoretic device, the method comprising:
- forming a plurality of fibrous structures, wherein each of the plurality of fibrous structures comprises two or more superposed fibers that extend in an identical direction or different directions;
- and
- forming a porous layer by adding non-migrating particles to the plurality of fibrous structures and dispersing the non-migrating particles in the plurality of fibrous structures,
- wherein the two or more superposed fibers are adhered to each other at one or more points of contact between the two or more superposed fibers to form one of the plurality of fibrous structures.
A display unit comprising:
- an electrophoretic device between a pair of bases, the pair of bases each being provided with an electrode, the electrophoretic device comprising:
- in an insulating liquid:
- a plurality of electrophoretic particles;
- and
- a porous layer formed of a plurality of fibrous structures, the plurality of fibrous structures comprising a plurality of non-migrating particles,
- wherein each of the plurality of fibrous structures comprises two or more superposed fibers extending in an identical direction or different directions, and wherein the two or more superposed fibers are adhered to each other at one or more points of contact between the two or more superposed fibers to form one of the plurality of fibrous structures.
