Abstract:
1. An electrochromic display device comprising: a substrate comprising a dividing wall and a concave portion surrounded by the dividing wall; a first electrode formed on a bottom surface of the concave portion; an electrical line formed on the dividing wall to electrically connect the first electrodes within adjacent concave portions to each other in a predetermined direction; a second electrode disposed opposite to the first electrode; a first color-development layer, a second color-development layer, and an electrolyte layer formed between the first and second electrodes; and an insulating layer formed on the electrical line on the dividing wall, wherein the first and/or second color-development layer includes a π-electron based conjugated polymer film derived from a π-electron based conjugated monomer, and the π-electron based conjugated monomer includes at least one compound selected from a group consisting of: aniline; a π-electron based conjugated monomer having a structure capable of introducing boron in a principal chain; a π-electron based conjugated monomer in which part of carbon of an aromatic ring is replaced by oxygen and which is typified by pyran; a benzene derivative selected from a group consisting of 2,3-dialkyl phenyl, 2,5-dialkyl phenyl, 2,3,5,6-tetraalkyl phenyl, 2,3-alkoxy phenyl, 2,5-alkoxy phenyl, 2,3,5,6-tetraalkoxy phenyl, 2-(N,N,-dialkyl amino)phenyl, 2,5-di(N,N,-dialkyl amino)phenyl, 2,3-di(N,N,-dialkyl amino)phenyl, p-phenylene oxide, p-phenylene sulfide, p-phenylene amino, p-phenylene vinylene, and fluorene; an acene derivative selected from a group consisting of naphthalene, anthracene, tetracene, pentacene, hexacene, heptacene, naphthylene vinylene, peri-naphthalene, amino pyrene, and phenanthrene; a carbazole derivative including N-alkyl carbazole; a pyridine derivative selected from a group consisting of pyrimidine, pyridazine, triazine, pyrazine, chinoline, and purine; a furan derivative including 3-alkyl furan; a pyrrole derivative selected from a group consisting of N-alkyl pyrrole, ethylene-3,4-dioxy pyrrole, and propylene-3,4-dioxy pyrrole; a thiophene derivative selected from a group consisting of thiophene vinylene, alkyl thiophene, ethylene-3,4-dioxy thiophene, propylene-3,4-dioxy thiophene, thienothiophene, thienofuran, thienopyrazine, and isothianaphthene; and a π-electron based conjugated compound selected from a group consisting of acetylene, oxadiazole, thiazyl, selenophene, tellurophene, imidazole, oxazole, thiazole, pyrazole, isoxazole, isothiazole, benzotriazole, pyran, benzothiadiazole, and benzooxadiazole.
