  "textContent": "A head-up display includes a measuring unit and a light source unit and a control unit. The measuring unit measures a distance to an obstacle existing in a running direction of an own vehicle. The light source unit has an attaching portion capable of attaching to the own vehicle and projects light for displaying an image onto a projection portion to supply a viewer with the light through the projection portion. The control unit restricts display of all or a part of information if a distance, to right-hand or left-hand direction of the own vehicle perpendicular to the running direction, between the obstacle and the own vehicle is equal to or shorter than a predetermined criterion distance when the own vehicle has moved towards the running direction for a predetermined time or by a predetermined distance.",
