Patent ID: 7944606

Claim:
A display device comprising: a first substrate comprising: a first base having a surface; and a first electrode layer disposed on the surface and having at least one first electrode; a partition element disposed on the first substrate; a second substrate disposed on the partition element, wherein the partition element forms at least one accommodating room between the surface of the first base and the second substrate, the first electrode is adapted to forming an electric field in the accommodating room, and a plurality of sections of the first electrode parallel to the surface of the first base are gradually reduced in a direction towards the second substrate; a dielectric liquid disposed in the accommodating room, wherein the dielectric liquid has a first dielectric constant; a plurality of first dielectrophoretic particles dispersed in the dielectric liquid, each of the first dielectrophoretic particles having a first color and a second dielectric constant different from the first dielectric constant; and a plurality of electrophoretic particles dispersed in the dielectric liquid, wherein each of the electrophoretic particles has a second color and the second color is different from the first color.
