An electrowetting display device comprising a plurality of pixel areas, wherein each pixel area is rectangular in shape and comprises: a hydrophobic surface on a bottom support plate; a first fluid and a second fluid on the hydrophobic surface, wherein the first fluid is immiscible with the second fluid and a top support plate covers the second fluid; a pixel electrode under a first part of the hydrophobic surface, wherein the pixel electrode has a shape which is a substantially U-shape or a substantially C-shape and comprises: a first arm having a first width, a second arm defined by a second width, a base portion defined by a height, wherein the first width and the second width are in a range of.02 -.2 a width W of the pixel electrode, the width W taken between an outer side of the first arm and an outer side of the second arm, and the height is in a range of.02 -.2 the width W of the pixel electrode, and an open end facing towards a side of the pixel area; a top electrode in contact with the second fluid; and a thin film transistor coupled to the pixel electrode and a voltage source, wherein voltage via the thin film transistor and the voltage source applied to the hydrophobic surface via a first signal line connected to the pixel electrode and a second signal line connected to the top electrode causes the hydrophobic surface to become more hydrophilic to thereby move the second fluid onto the first part of the hydrophobic surface to thereby substantially displace the first fluid from the first part of the hydrophobic surface to a second part of the hydrophobic surface without any pixel electrode thereunder. a hydrophobic surface on a bottom support plate; a first fluid and a second fluid on the hydrophobic surface, wherein the first fluid is immiscible with the second fluid and a top support plate covers the second fluid; a pixel electrode under a first part of the hydrophobic surface, wherein the pixel electrode has a shape which is a substantially U-shape or a substantially C-shape and comprises: a first arm having a first width, a second arm defined by a second width, a base portion defined by a height, wherein the first width and the second width are in a range of.02 -.2 a width W of the pixel electrode, the width W taken between an outer side of the first arm and an outer side of the second arm, and the height is in a range of.02 -.2 the width W of the pixel electrode, and an open end facing towards a side of the pixel area; a first arm having a first width, a second arm defined by a second width, a base portion defined by a height, wherein the first width and the second width are in a range of.02 -.2 a width W of the pixel electrode, the width W taken between an outer side of the first arm and an outer side of the second arm, and the height is in a range of.02 -.2 the width W of the pixel electrode, and an open end facing towards a side of the pixel area; a top electrode in contact with the second fluid; and a thin film transistor coupled to the pixel electrode and a voltage source, wherein voltage via the thin film transistor and the voltage source applied to the hydrophobic surface via a first signal line connected to the pixel electrode and a second signal line connected to the top electrode causes the hydrophobic surface to become more hydrophilic to thereby move the second fluid onto the first part of the hydrophobic surface to thereby substantially displace the first fluid from the first part of the hydrophobic surface to a second part of the hydrophobic surface without any pixel electrode thereunder.
