ABSTRACT:
A display device is provided for making images of a movie, a TV or the like invisible to a driver while the vehicle is traveling, but at the same time visible to a passenger riding in a front passenger seat. A viewing angle control shutter20using a liquid crystal is disposed facing a front surface of a liquid crystal display panel19. When the vehicle is in a stopping state, the viewing angle control shutter20is set to off, thereby making the image that is displayed on the display panel19visible from the driver's seat side and the front passenger seat side. While the vehicle is traveling, the viewing angle control shutter20is driven such that the driver can watch an image produced by the navigation device13, but cannot watch an image reproduced by a DVD reproduction device14.
