Abstract
A display device comprising picture elements, which are constituted by electrowetting elements having at least one first fluid and a second fluid immiscible with each other within a space between a first support plate and a second support plate, the second fluid being electro-conductive or polar. The first fluid in each element is at the side of the first support plate confined by element walls, and the second fluid is shared by a plurality of picture elements, characterized by a preventer for preventing first fluid portions from being expelled from its confinement when forces other than electrowetting forces are exerted on this fluid.
