Abstract
An electrophoretic display utilizing a phenomenon of electrophoresis is provided. The electrophoretic display includes an lower electrode located on an under layer, an lower electrode protection layer formed on the lower electrode, a plurality of microcapsules located on the lower electrode protection layer, coated or encapsulated in a micro size and not operating in an electric field, a particle and/or a fluid included within the microcapsule and having a single visual color, a charged particle existed among the plurality of microcapsules, having different visual colors, operating according to an electric field and suspended in a dielectric fluid, and an upper electrode protection layer and an upper electrode located on the plurality of microcapsule in sequential order. Accordingly, a reliable electrophoretic display with one color or natural colors is achieved.
