An object of the present invention is to provide a driving support system and a display device that is optimal for the driving support system. According to this driving assistance system, it is possible to quickly recognize a change in the state of mind and body of the driver and to give attention by giving a warning light indication in the driver's forward field of view. In addition, the light emitting device used in this driving assistance system makes it possible to see the background across the display. Further, by adjusting the movable polarizing plate, display switching can be appropriately performed between the transmission mode and the non-transmission mode. |
