Claims
- 1. An electrophoretic display comprising:
a plurality of microcapsules disposed between a pair of substrates, wherein each microcapsule comprises an insulating colored fluid and charged particles dispersed in the colored fluid, and the microcapsules contact at least the substrate arranged at a display face side of the pair of substrates.

disposing a spacer between the pair of substrates to bond the pair of substrates, the spacer having a diameter which is smaller than the diameter of the microcapsules; and fixing the pair of substrates while pressing the substrates so that the microcapsules contact the pair of substrates.
- 4. A method for making an electrophoretic display including a plurality of microcapsules disposed between a pair of substrates, the method comprising:
applying a microcapsule dispersion material including a binder and microcapsules dispersed in the binder on the substrate lying at the display face side of the pair of substrates and drying the substrate; and bonding the pair of substrates.
- 5. The method for making an electrophoretic display according to claim 4, wherein the binder comprises an emulsion adhesive and water;
the microcapsule dispersion material is compounded so that the microcapsule dispersion material contains 50% or less by weight of the microcapsules, and the emulsion adhesive after drying contains 10% by volume or less of the microcapsules; and the microcapsule dispersion material is applied to a thickness which is one to three times the diameter of the microcapsules.
- 6. An electronic apparatus comprising the electrophoretic display according to claim 1.
- 7. An electrophoretic display comprising:
a pair of substrates; and a plurality of microcapsules in which a plurality of particles and fluid are contained, the microcapsules arranged between the substrates, wherein each of the plurality of microcapsules is different in shape and in contact with each other.
- 8. The electrophoretic display of claim 7, wherein each of the microcapsules is deformed so as to fill gaps formed therebetween.
- 9. The electrophoretic display of claim 7, wherein the plurality of particles are electrically charged and the fluid is colored.
- 10. The electrophoretic display of claim 7, wherein the plurality of particles comprise a first group of particles and a second group of particles; and
the particles of the first group are positively charged and the particles of the second group are negatively charged.
- 11. The electrophoretic display of claim 10, wherein the first group of particles and the second group of particles are different in color.
- 12. The electrophoretic display of claim 11, wherein the fluid is transparent.
- 13. An electronic apparatus comprising the electrophoretic display of claim 10.
- 14. An electrophoretic display comprising:
a first substrate including an electrode and a second substrate including an electrode opposing the first substrate, the electrodes providing an electric field therebetween; and a plurality of microcapsules dispersed in a binder arranged between the substrates, the plurality of microcapsules each including a first group of charged particles and a second group of charged particles dispersed in a fluid, the first group of charged particles having a charge opposite to the charge of the second group of charged particles, wherein the first group of charged particles migrate in a direction of the electric field and the second group of charged particles migrate in a direction opposite of the electric field.
- 15. The electrophoretic device of claim 14, wherein the first group of charged particles are a first color and the second group of charged particles are a second color.
- 16. The electrophoretic device of claim 14, wherein the first group of charged particles are positively charged and the second group of particles are negatively charged.
- 17. The electrophoretic device of claim 14, wherein each of the microcapsules is deformed so as to fill gaps formed therebetween.
- 18. An electronic apparatus including the electrophoretic device of claim 14.
- 19. An electrophoretic device comprising:
a first substrate including a first electrode; a second substrate including a second electrode, the first and second electrode providing a positive or a negative electric field therebetween; a microcapsule dispersion material including a plurality of microcapules and an emulsion adhesive that is compounded so that the microcapsule dispersion material contains 50% or less by weight of the microcapsules, and the emulsion adhesive after drying contains 10% by volume or less of the microcapsules; and each of the microcapsules containing at least one first particle and at least one second particle dispersed in a fluid, the first particle being positively charged and the second particle being negatively charged such that when the positive electric field is provided, the first particle is migrates away from a direction of the electric field and the second particle migrates toward the direction of the electric field.
- 20. The electrophoretic device of claim 19, wherein the first particle is a first color and the second particle is a second color.
- 21. The electrophoretic device of claim 19, wherein each of the microcapsules is deformed so as to fill gaps formed therebetween.
- 22. An electronic device including the electrophoretic device of claim 19.
