The invention is a display device comprising a solid top transparent,
charge conducting material, positioned below the transparent solid
material is an active layer comprising an electrochromic material and an
electrolyte, and positioned below the active layer is a working electrode
and a counter-electrode arranged to be isolated from one another, wherein
the distance between the working and the counter electrode is greater
than two times the thickness of the active layer between the electrode
and the conductive material.
