  • Patent number: 11009702
    Abstract: A display device includes a controller configured to cause the image generator to generate a virtual image on the basis of at least a state of a vehicle and to adjust the depression angle on the basis of a reception result of a first receptor configured to receive adjustment of the depression angle of the position at which the virtual image is visually recognized by the viewer, wherein, when the depression angle has been adjusted on the basis of a reception result of the first receptor in a case in which the virtual image visual recognition distance is not a predetermined distance, the controller is configured to set the adjusted depression angle as a minimum depression angle and is configured to cause the image generator to generate a virtual image such that the depression angle does not become less than the set minimum depression angle.
