Abstract
An electrophoresis dispersion liquid according to the aspect of the invention contains at least one type of electrophoretic particles and a dispersion medium and, in the electrophoresis dispersion liquid, the content of the electrophoretic particles is 10 weight % or more to 30 weight % or less. Furthermore, the electrophoretic particles have base particles and a polymer (particle surface treatment agent) linked with the base particles and, in the electrophoretic particles, the content of the polymer is 5 weight % or more to 15 weight % or less.

An electrophoresis dispersion liquid comprising:
- at least one type of electrophoretic particles;
- and
- a dispersion medium,
- wherein,
- in the electrophoresis dispersion liquid, a content of the electrophoretic particles is 10 weight % or more to 30 weight % or less,
- the electrophoretic particles have base particles and a particle surface treatment agent linking with at least one of the base particles,
- the particle surface treatment agent has a dispersion portion derived from a silicone macromonomer represented by General Formula (I) below
- where R1 represents a hydrogen atom or a methyl group, R2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, R3 represents a structure which includes one type out of an alkyl group having 1 to 6 carbon atoms and an ether group of ethylene oxide or propylene oxide, and n represents an integer of 0 or more, and
- a content of the particle surface treatment agent in the electrophoretic particles is 5 weight % or more to 15 weight % or less.
An electrophoresis dispersion liquid comprising:
- first electrophoretic particles;
- second electrophoretic particles with a smaller particle diameter than the first electrophoretic particles;
- and
- a dispersion medium,
- wherein,
