Abstract

Electrowetting display devices and fabrication methods thereof are presented. The electrowetting display device includes a first substrate and a second substrate with a polar fluid layer and a non-polar fluid layer insolvable to each other and interposed between the first and second substrates. A first transparent electrode is disposed on the first substrate. A second electrode is disposed on the second substrate. A dielectric layer is disposed on the second electrode. A hydrophilic partition wall structure is directly disposed on the dielectric layer defining a plurality of pixel regions. A layer of low surface energy material is disposed on the dielectric layer within each of the pixel region.
