Abstract
Electrowetting display devices are presented. The electrowetting display includes a first substrate and an opposing second substrate with a transparent polar fluid layer and an opaque non-polar fluid layer insoluble with each other and interposed between the first and second substrates. A first transparent electrode is disposed on the first substrate. A second transparent electrode is disposed on the second substrate. A dielectric layer is disposed on the second transparent electrode. A reflective plate structure is interposed between the second transparent electrode and the second substrate, thereby defining a reflective region and a transmission region. A backlight plate is disposed on the back of the second substrate. During operation, the opaque non-polar fluid converges, therefore, exposing equal areas of reflective region and transmission region.
