摘要： An HUD apparatus is configured to irradiate light for forming an image on a transmissive reflector provided in a movable body, and to display a virtual image in a display area to overlap the virtual image with scenery outside the movable body. A given distance range in the scenery from a reference point that is set in the movable body is included in the display area, and a difference between a first convergence angle to a target object (e.g., road surface) that is present in the given distance range and a second convergence angle to the virtual image displayed in the display area is at most one degree.
