ABSTRACT:
A layer composition of an electrowetting system with a first electrode layer, an insulator layer on the first electrode layer, and a fluid layer over the insulator layer, wherein the fluid layer comprises at least two immiscible fluids which, under the influence of an applied voltage, reversibly change their wetting behavior of a surface allocated to the insulator layer, wherein the insulator layer being at least in part built of a material with a permittivity of ∈r≧20. The fluid layer is adjacent to at least one layer being repellent for the at least one of the fluids. On the surface of the repellent layer pointing away from the fluid layer is provided an adhesion enhancing layer before the subsequent layer.
