Abstract
An electrowetting display includes first and second substrates facing each other, an electrowetting layer, a first electrode, a second electrode, and a hydrophobic barrier layer. The electrowetting layer is disposed between the first substrate and the second substrate and includes a first fluid and a second fluid, and the first fluid has an electrical conductivity or a polarity. The first electrode is disposed on the first substrate, and the second electrode forms an electric field in cooperation with the first electrode to control a position of the first fluid. The hydrophobic barrier layer is disposed between the first substrate and the electrowetting layer to cover the first electrode and includes a first surface making contact with the first electrode and a second surface having a hydrophobicity stronger than a hydrophobicity of the first surface and making contact with the electrowetting layer.
