Abstract

An electrowetting element comprising a first support plate, a second support plate and a first and second fluid located between the first support plate and the second support plate, the second fluid immiscible with the first fluid. The first support plate comprises a wall extending along at least part of a perimeter of the electrowetting element and an electrode comprising a first electrode portion having a first electrode portion area and a second electrode portion having a second electrode portion area larger than the first electrode portion area. The first electrode portion is closer to the second support plate than the second electrode portion. The first electrode comprises a first edge portion and a second edge portion positioned further from an inner surface of a wall in a direction substantially perpendicular to the inner surface of the wall than the first edge portion.
