PROBLEM TO BE SOLVED: To provide a three-dimensional display device for advertisement which does not require any mold and is not subjected to the process of heat forming after print and is prevented from deformation of a print previously provided on the surface of a sheet and is formed like a sheet so that plural display devices can be closely piled up and shipped and reduces transporting and packing expenses. SOLUTION: A sheet 1 provided with the print on at least one side face and a cut 2 provided in the sheet 1 are provided, and a part piece on either side of the cut 2 is so formed that it can be contracted, and this contractible part piece 4 is shortened to curve or bend a part piece 6 on the other side of the cut 2, and thus the sheet is made three-dimensional.
