Abstract
An optical switch, e.g., a display device based on layer break up or layer displacement having at least two different states, in which one of the fluids, e.g., oil in a first state, adjoins at least a first support plate and, in the second state, the other fluid at least partly adjoins the first support plate, in which picture elements are separated by areas having a hydrophilic surface.
