Abstract

The present invention relates to electrowetting optical element, a method of manufacturing and a display comprising such elements. In accordance with an aspect of the invention the electrowetting optical element comprises: a containment space for containing a polar liquid relative to a non-polar liquid, wherein said polar liquid and said non-polar liquid being immiscible with each other; a first electrode layer stack defining a first enclosing surface of said containment space, and comprising a substrate, a first electrode layer, and an insulating layer having a hydrophobic first interface layer with said containment space; a second electrode layer stack defining a second enclosing surface of said containment space, and comprising a superstrate and a second electrode layer having a second interface layer with said containment space and one or more cell walls, being fixedly mounted on said second electrode layer stack and extending towards said first electrode layer stack, for defining sides of said containment space, and wherein an end face of said one or more cell walls adjacent said first electrode layer stack faces said hydrophobic first interface layer in a loose manner; wherein said second electrode layer stack comprises a thin film transistor electrode layer, and wherein said one or more cell walls are comprised of an electrically insulating material.
