Abstract
An electrochromic device comprising a solid layered structure. The structure includes a pair of electrodes and an electrochromic layer sandwiched between the pair of electrodes. The device is sandwiched between a pair of vitreous sheets of which at least one is transparent with a reservoir of ionizable material being held between the sheets. On application of an electrical potential between the electrodes, ions are permitted to migrate between the ionizable material and the electrochromic layer.
