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