All-solid-state electrochromic windows which have complementary color transition were assembled by employing poly(aniline-N-butylsulfonate)s (PANBS), photo polymerizable electrolyte and poly(3,4-ethylenedioxythiophene) (PEDOT) in sequence. Each electrochromic layer thickness was controlled in nano-scale in order to balance charges between the electrodes generated from the electroactive layers. The electrochromic (EC) properties were characterized using cyclic voltammetry, chronocoulometry and UV-Vis spectroscopy. Absorbance change and coloration efficiency were dependant on charge density and an all solid state EC display based on an optimized thickness showed EC response at 2.4 V within 5 s with a stable memory effect.
