In a display device including: an upper space (display space)provided on a display surface side; and a colored liquidthat is sealed inside the upper spaceso as to be operable and is colored in a predetermined color, which is structured so as to be able to change a display color on the display surface side according to application of an electric field to the colored liquid, the colored liquidcontains a conductive liquid as a dispersion medium and a pigment of a self-dispersing type as a coloring agent. Thereby, the display device that can improve display quality and have high durability that enables to maintain an excellent displaying function over a long period of time, and the electric apparatus using the display device can be provided.

The invention provides a method and an apparatus for manufacturing a developer, which can manufacture a developer having a uniform and fine particle shape in a narrow particle size distribution and having a coloring agent highly dispersed therein at the primary particle level, the method and apparatus at the same time enabling continuous and efficient production without opening and closing a reactor. The method comprises the steps of: dissolving a binding resin component in a supercritical or subcritical fluid so that the binding resin component is blended with a coloring agent component; and reducing the solubility of the binding resin component in the supercritical or subcritical fluid so that the binding resin component is precipitated in the form of particles with the coloring agent component dispersed in the interior thereof. In the aforementioned method and apparatus, the reactor provided with at least a stirring mechanism and a mechanism for discharging dissolved components has a developer material carrier comprising a mesh that prevents the passage of treated materials and allows the passage of the supercritical or subcritical fluid.

Method and apparatus for manufacturing developer, and developer

In a display device that includes a display space provided on a display surface side and a liquid sealed inside the display space so as to be operable and is constituted so as to be able to change a display color on the display surface side according to an application of an electric field to the liquid, the liquid is an ionic liquid containing an ambient temperature molten salt combining a cation and an anion. Further, an amount of water blended in the liquid is 0 to 10 parts by weight with respect to 100 parts by weight of the ionic liquid. This makes it possible both to reduce a voltage to be applied to the liquid so as to allow driving at a low voltage and to improve an operation performance.
