A display device is provided to reduce the number of components and be simplified by not using a motor and a gear device for the automatic rotation of a supporting member. A coil shaft(410) forms a magnetic field by receiving electric current, and a magnet(420) is spaced from the coil shaft and surrounds the coil shaft. A supporting member(200) supports a display body by being coupled with the display body and rotates by the electromagnetic force between the coil shaft and the magnet. A power supplying unit(230) rotates the supporting member in a forward or reverse direction by supplying the current to the coil shaft in a forward or reverse direction. The coil shaft forms the magnetic field in a columnar direction by making the current flow in its length direction. |
