Abstract
A display includes a first substrate, a partition element, a second substrate, a dielectric liquid, a plurality of dielectrophoretic particles and a plurality of electrophoretic particles. The partition element is disposed on the first substrate. The second substrate is disposed on the partition element. The partition element forms at least one accommodating room between the first substrate and the second substrate. The first substrate or the second substrate is adapted to forming an electric field in the accommodating room. 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 first color and a second dielectric constant different from the first one. The electrophoretic particles are dispersed in the dielectric liquid. Each of the electrophoretic particles has a second color different from the first one. Another display is also provided.
