1. A display device comprising:
a control circuit that determines a mode of inclination of a display object that is an image shaped to point to one direction, and that further determines a position of the display object visually recognized by a user in a vehicle; and
a projector that projects light representing the display object in the mode of inclination determined by the control circuit onto a display medium provided in the vehicle, to cause the light to be reflected off the display medium toward the user in the vehicle to enable the user to visually recognize the display object in the mode of inclination as a virtual image through the display medium,
wherein the control circuit determines the mode of inclination of the display object that points to the one direction as a navigation direction, by controlling a yaw angle and a roll angle of the display object in accordance with an attribute of a path point that is set on a path for navigation of the vehicle to a destination,
wherein the attribute includes a direction of the path at the path point or a position of the path point,
wherein a depth position of the display object in a traveling direction of the vehicle is placed between a current position of the vehicle on the path and the path point, and
wherein the control circuit moves a lateral position of the display object in a lateral direction of the vehicle towards a right/left turn direction indicated by the navigation direction when a distance from a current location of the vehicle to a right/left turn point, which is a point of intersection that allows a right or left turn on the path, is less than or equal to a first threshold value.
