An electronic device is provided. The electronic device includes a first substrate. The electronic device also includes a multilayer electrode disposed on the first substrate. The multilayer electrode includes a first conductive layer, a second conductive layer disposed on the first conductive layer, and a third conductive layer disposed on the second conductive layer. The electronic device further includes a second substrate facing the first substrate. In addition, the electronic device includes a working medium disposed between the first substrate and the second substrate. The chemical electromotive force of the second conductive layer is between that of the first conductive layer and the third conductive layer.
