Claim 0:
1. An electrochromic device, which comprises a light transmission variable structure interposed between a first base layer and a second base layer,
wherein the light transmission variable structure comprises a first chromic layer and a second chromic layer,
an electrolyte layer is interposed between the first chromic layer and the second chromic layer,
wherein an elongation of the electrochromic device is 60% to 170%,
wherein the second chromic layer comprises an oxidizing chromic material and a polymer resin,
wherein the second chromic layer comprises 0.1 to 5 parts by weight of the polymer resin relative to 100 parts by weight of the oxidizing chromic material,
wherein the electrochromic device comprises a first barrier layer and a second barrier layer, and the first barrier layer and the second barrier layer each comprises at least one selected from the group consisting of metal oxides, metal nitrides, metal oxynitrides, metalloid oxides, metalloid nitrides, metalloid oxynitrides, and combinations thereof,
wherein the polymer resin is one or more selected from the group consisting of a urethane acrylic-based resin, a silicone-based resin, an acrylic-based resin, an ester-based resin, an epoxy-based resin, a phenolic-based resin, a poly urethane-based resin, a polyimide-based resin, and an ethylene vinyl acetate-based resin, and
wherein the oxidizing chromic material is one or more selected from the group consisting of nickel oxide, manganese oxide, cobalt oxide, iridium-magnesium oxide, nickel-magnesium oxide, titanium-vanadium oxide, a Prussian blue based pigment, and combinations thereof.
