Abstract

An electrochromic glazing containing: a substrate including a layer structure thereon, which contains a first and second electrode layer, between which a first and second electrochemically active layer are situated, which each reversibly incorporate ions, wherein the first active layer contains an electrochromic material and the two active layers are separated from each other by an electrolyte layer, the layer structure being subdivided into series-connected electrochromic cells by a transition zone comprising: a first trench; a second trench; and a third trench between the first and second trenches, wherein the first and second trenches subdivide the first and second electrode layers into first electrode sections electrically insulated from each other and second electrode sections electrically insulated from each other, respectively, and the third trench is filled with an electrically conductive material, by which the first and second electrode sections of the cells adjacent the transition zone are electrically connected.
