An electrowetting display device comprises a first support plate comprising a first electrode and a second support plate. A seal connects the first support plate to the second support plate. A first fluid and a second fluid, immiscible with the first fluid, are located between the first and second support plates. A second electrode is in electrical contact with the second fluid. An electrical connector connects the first electrode to the second electrode. A barrier structure at least partly surrounds the electrical connector. The electrical connector and the barrier structure are separated from the first fluid and the second fluid by the seal.
