Abstract:
1. An electrowetting display device comprising: a first substrate and a second substrate; intersecting pixel walls disposed on an area of the first substrate, wherein the intersecting pixel walls partition the area of the first substrate into pixel areas; a partition wall that partitions each of the pixel areas into a plurality of sub-pixel areas; a hydrophobic layer disposed in each of the sub-pixel areas; an electrowetting region between the first substrate and the second substrate and disposed in each of the sub-pixels and including a first fluid and a second fluid that are immiscible with each other, the second fluid having an electrical conductivity or a polarity; a first electrode on the first substrate, wherein the first electrode at least partially overlaps each of the sub-pixel areas of each of the pixel areas; and a second electrode on the second substrate, wherein the second electrode at least partially overlaps two or more of the pixel areas, and wherein the second electrode is in electrical communication with the first electrode to generate an electric field in the electrowetting layer.
