Layer composition of an electrowetting system

A layer composition of an electrowetting system, comprising

• a first carrier made of a transparent insulating material;
• a first electrode layer disposed over the first carrier;
• an insulator layer over the first electrode layer being built, at least in parts, of a material with a permittivity of ∈r≧20;
• a first repellent layer over the insulator layer that is repellent for at least one fluid that adjoins to the repellent layer;
• a fluid layer on the first repellent layer, wherein the fluid layer comprises at least two non-mixable fluids which, under the influence of an applied voltage, reversibly change their wetting behavior towards a surface of the first repellent layer;
• and
• a second repellent layer disposed over
• a first adhesive layer disposed over
• a second electrode layer disposed over
• a second carrier;
• wherein the first carrier, the first electrode layer, the insulator layer and the first repellent layer form a first section, and the second repellent layer, the first adhesive layer, the second electrode layer and the second carrier form a second section, with the first and second section forming a sandwich around the fluid layer,
• wherein a second adhesive layer is disposed between the insulator layer and the first repellent layer, and
• wherein the adhesion enhancing layer comprises SinH2n+2 or SinH2n (n≧1) or a mixture thereof.
