Disclosed are an electrochromic photonic-crystal reflective display device and a method of manufacturing the same. The electrochromic photonic-crystal reflective display device includes a substrate having lower electrodes, a first solid polymer electrolyte thin film, a block copolymer photonic-crystal thin film, a second solid polymer electrolyte thin film, and upper electrodes. The first solid polymer electrolyte thin film is formed on the top of the substrate, and is made from a mixed solution including a polymer electrolyte and an ionic liquid. The block copolymer photonic-crystal thin film is formed on the top of the first solid polymer electrolyte thin film. The second solid polymer electrolyte thin film is formed on the top of the block copolymer photonic-crystal thin film, and is made from a mixed solution including a polymer electrolyte and an ionic liquid. The upper electrodes are formed on the top of the second solid polymer electrolyte thin film.
