Abstract
An electro-wetting display device includes a polar fluid layer, a pixel electrode, a non-polar black fluid layer, a driving electrode, and a color fluid layer. The non-polar black fluid is deformed by a voltage difference between a voltage applied to the pixel electrode and a voltage applied to the polar fluid layer. the non-polar color fluid is deformed by a voltage difference between a voltage applied to the driving electrode and a voltage applied to the polar fluid layer. The driving electrode receives a voltage having a voltage level varied according to a display mode.
