PROBLEM TO BE SOLVED: To provide an efficient display device that has a plurality of sheet-like light emitting elements provided in a small area, and can automatically supply power only to a sheet-like light emitting element desired to view.SOLUTION: A display device 1 has a binder-like structure in which a plurality of light emitting sheet bodies 5 having a light emitting part 7 is movably held by a reverse U-shaped holding body 3. Wiring to be connected to the light emitting part constitutes an induction coil 9 around a hole of the light emitting sheet body into which the holding body is inserted. A plurality of detection coils 15 is arranged inside the holding body. When a guide signal is given to the induction coil of each light emitting sheet body by controlling a power source, and a detection signal flowing to each detection coil existing inside the holding body is detected at the same timing as with the guide signal given, a position of the light emitting sheet body can be specified. The power is supplied only to the light emitting part of the sheet body present at an uppermost part of a first holding body 3a to emit the light emitting part. |
