Abstract
Electrowetting display devices are presented. The electrowetting display includes a first substrate and an opposing second substrate with a polar fluid layer and a color non-polar fluid layer interposed therebetween. A first transparent electrode is disposed on the first substrate. A second electrode is disposed on the second substrate. A hydrophilic partition structure is disposed on the second substrate, thereby defining a plurality of sub-pixels. The color electrowetting display further includes an array of color pixel regions. Each pixel region consists of a set of primary color sub-pixel. Each color sub-pixel corresponds to one of different color non-polar fluid layers, and each of the different color non-polar fluid layers is isolated from each other. The colors of non-polar fluid layer in the neighboring sub-pixels are different.
