Abstract
A charged particle to be used for an electrophoretic display medium in which a first attached material being charged with a predetermined polarity and a second attached material having a smaller adhesion force than that of the first attached material are attached to a mother particle, wherein the first attached material is a minute particle (hereinafter referred to as “first minute particle”), and the outermost surface of the second attached material is located outward relative to the outermost surface of the first minute particle in the radial direction of the mother particle, is provided.
Claims12
A charged particle used for an electrophoretic display medium in which a first attached material being charged with a predetermined polarity and a second attached material having a smaller adhesion force than that of the first attached material are attached to a mother particle, wherein the first attached material is a minute particle (hereinafter referred to as “first minute particle”), and the outermost surface of the second attached material is located outward relative to the outermost surface of the first minute particle in the radial direction of the mother particle.
A charged particle used for an electrophoretic display medium in which a first attached material being charged with a predetermined polarity and a second attached material having a smaller adhesion force than that of the first attached material are attached to a mother particle, wherein the first attached material is a minute particle (hereinafter referred to as “first minute particle”), and when an end portion that is most distant from the center of the charged particle is called an outer end portion, the distance from the center of the charged particle to the outer end portion of the second attached material is longer than the distance from the center of the charged particle to the outer end portion of the first minute particle.
A charged particle used for an electrophoretic display medium in which a first minute particle being charged with a predetermined polarity and a second minute particle having a smaller surface adhesion force than that of the first minute particle are attached to a mother particle,
- wherein when the charged particle comes into contact with another surface, the second minute particle contacts with the surface, and the mother particle and the first minute particle do not come into contact with the surface.
