First Claim
1. An optical switch having at least one first fluid (5) and a second fluid (6) immiscible with each other within a space between a first transparent support plate (3) and a second support plate (4), the second fluid being electroconductive or polar, the comprising on at least one of the substrates a first electrode (7) only partly covering the total area of the optical switch.

Abstract
An optical switch, e.g. a display cell based on layer displacement or layer break up having at least two different states, in which one of the fluids (5) e.g. oil in a first state adjoins at least a first support plate (3) and in the second state the other fluid (6) at least partly adjoins the first support plate. Part of an otherwise homogeneous electrode (7) is removed to realize oil motion control.
