PROBLEM TO BE SOLVED: To provide a reflective display device that can stably switch between coloring and decoloring by using a leuco dye and that can stably switch between a display mode and an erasure mode of a pixel.SOLUTION: The reflective display device includes a first substrate 1 formed of a transparent material, a first electrode 2 disposed on one surface of the first substrate and formed of a transparent material, a second substrate 8 disposed to oppose to the first electrode side of the first substrate, and a second electrode 7 disposed on the first substrate side of the second substrate. The reflective display device includes, between the first electrode and the second electrode and from the first electrode side, at least a leuco dye layer 3, a cation exchange film 4, an electrolyte layer 6, and a cation retention layer 6. 【課題】ロイコ染料を用いて安定的に発色と消色を切り替え、安定的に画素の表示と消去を切り替えることができる反射型表示装置を提供する。【解決手段】透明な材料によって形成された第１の基板１と、第１の基板の一方の面に設けられ、透明な材料により形成された第１の電極２と、第１の基板の第１の電極側に対向するように設けられた第２の基板８と、第２の基板の第１の基板側の面に設けられた第２の電極７と、を備え、第１の電極と第２の電極との間には、第１の電極側から、少なくとも、ロイコ染料層３、陽イオン交換膜４、電解質層５、及び陽イオン保持層６がこの順に設けられた、反射型表示装置。【選択図】図１
