Abstract

A display device includes a first shape-memory wire that memorizes an extended state and a second shape-memory wire that memorizes a bending state. The laminated layers include a first flexible layer, a second flexible layer, and a display element layer on which light emitting elements are disposed. The first flexible layer includes a first interface between the first flexible layer and a layer in contact with an upper side or a lower side of the first flexible layer. The second flexible layer includes a second interface between the second flexible layer and a layer in contact with an upper side or a lower side of the second flexible layer. The first shape-memory wire is disposed within the first flexible layer or on the first interface. The second shape-memory wire is disposed within the second flexible layer or on the second interface.
