(57) [Problem] To provide an EC display that can be easily made full-color, has excellent memory characteristics, and has greatly improved response speed, coloring efficiency, and repeated durability. SOLUTION: Between a pair of transparent electrodes in which a semiconductor nanoporous layer having a specific surface area of 1 to 5000 m 2 / g is formed on at least one surface is disposed so that the semiconductor nanoporous layers face each other. An EC display having an electrolyte layer sandwiched therebetween and having either a passive matrix panel structure or an active matrix panel structure, wherein the electrolyte layer is reversible by at least one of an electrochemical oxidation reaction and a reduction reaction. It is an EC display that contains at least one EC dye that develops or decolors. |
