Abstract:
1. A device comprising: a rigid or flexible support substrate; a transparent electrode provided on the rigid or flexible support substrate, the electrode including a grid network of electrically-conductive lines comprising nodes and links extending through a central viewing area of the substrate; a transparent colored layer provided between the rigid or flexible support substrate and the transparent electrode to reduce optical impact of the transparent electrode; and an electrochromic functional layer on a surface of the substrate, the electrode being in contact with the electrochromic functional layer, wherein the lines joining up at each node are bent in a shape of an arc or in a wavy shape, the grid network including three lines that join up at each node, wherein each of the three lines is curved in a shape of an arc, and the lines of the grid network have a width between 5 and 20 μm, the lines of the grid network either always having a same width or locally having different widths.
