Abstract:
1. An electrowetting display device comprising: first and second substrates facing each other and separated from each other; a cell region between the first and second substrates, the cell region including a pixel region and a reservoir region; a first fluid and a second fluid in the cell region, the first fluid being conductive and flowing according to an electrowetting principle and the second fluid being non-conductive and not mixed with the first fluid; an electrode unit turning on and off the pixel region, the electrode unit including a pixel electrode coated with an insulating material and at least one reservoir electrode coated with the insulating material to promote flow of one of the first fluid and the second fluid into the reservoir region; and a partition unit on the first substrate, the partition unit defining the cell region and including a first surface facing outward from the cell region, a second surface facing the cell region, and a third surface connecting the first and second surfaces and facing upward from the cell region, wherein the reservoir region is in a region between the first and second surfaces of the partition unit.
