Abstract:
1. A color electrophoretic display, comprising: a plurality of lower electrodes arranged on a lower layer and disposed with a predetermined interval therebetween; a plurality of first to third photoresist chambers arranged on the plurality of lower electrodes wherein the first to third photoresist chambers have a size equal to or less than that of a pixel; first to third electronic inks accommodated in the plurality of first to third photoresist chambers respectively, and discriminatively operating to an electric field to independently display red, green, and blue colors; a plurality of upper electrodes disposed with a predetermined interval therebetween and facing the plurality of lower electrodes with the plurality of first to third photoresist chambers being held therebetween; and the first to third electronic inks which are composed of pairs of charged particles having red, green, blue colors, or cyan, magenta, yellow colors and charged particles having a white color, or pairs of two charged particles having a black color and a white color, are dispersed in a dielectric fluid; wherein the first to third photoresist chambers have a width of 50 to 300 nm.
