A display device including a insulating substrate, an organic layer disposed on the insulating substrate, a common electrode disposed on the organic layer and a bead layer including a plurality of beads through which light from the organic layer passes. Other embodiments may be described and claimed. The creation of internal magnetic fields generated by the flow of the induced electrical current gives rise to the structure’s magnetic properties. The invention makes it possible to efficiently and properly form a thin film having a multi-step structure by a single process. The controller selectively controls the first and second content displayed by the first and second display devices, respectively, in response to the command.
