PROBLEM TO BE SOLVED: To suppress deterioration in communication performance of an antenna while ensuring easy and reliable connection between an information display layer and the antenna.SOLUTION: Electronic paper 30 and an antenna 51 are electrically connected and provided together on one surface of an electrode substrate 40 and a controller substrate 50. With the vicinity of a connection part of the controller substrate 50 and the electrode substrate 40 as a folding part, it is folded so as to make the surface on which the electronic paper 30 and the antenna 51 are provided together face outside, so that the electronic paper 30 and the antenna 51 face with each other via the electrode substrate 40 and the controller substrate 50.
