All-solid-state electrochromic devices which have complementary blue color transition were assembled by employing PAS (Poylaniline sulfonate), photo polymerizable electrolyte and thiophene derivatives in sequence. Electrochromic thin layers on indium-tin oxide (ITO) substrate were fabricated by spin coating or electrochemical polymerization. The thickness of the films were changed in order to achieve larger optical density difference and faster response time. The characterizations were studied using cyclic voltammetry and UV-Vis spectroscopy. Higher color contrast was observed in a dual EC electrode system than a single one. An all solid state EC display based on an optimized thickness and composition showed EC response at 3V within 5s with a stable memory effect.
