Display panels are located in a predetermined arrangement to form a screen in a display device. A driver circuit is independently attached to each of the display panels in the display device. The driver circuit outputs a driving signal to the display panel in response to the reception of a radio signal. The display changes on the individual display panel in response to the reception of the driving signal. A radio signal is utilized to renew the display. Wiring is not required to extend from the display panel. This results in a simplified structure of the display device.
