Patent ID: 8730555

Claim:
An electrowetting display device comprising: a plurality of picture elements having a first support plate and a second support plate and a space between the first support plate and the second support plate, the space including at least one first fluid and a second fluid immiscible with each other, the second fluid being electroconductive or polar; the first support plate including at least one electrode for applying an electric field extending from the second fluid to the at least one electrode and a layer arranged on a side of the at least one electrode facing away from said space, the layer forming an electronic component for applying a voltage to the at least one electrode and the electronic component being any of a control line, a capacitor or a further electrode, the further electrode being arranged for applying an electric field extending from the second fluid to the further electrode; wherein the at least one electrode comprises a height difference corresponding to a thickness of the layer and determining a preferred direction of motion of the first fluid in a direction of increasing distance between the at least one electrode and the second support plate.
