An image display device includes a light illuminator, a crossing-facility detector, an image position determiner, and an illumination controller. The light illuminator is configured to send out light frontward of a first vehicle as an own vehicle, to display an image for a pedestrian. The crossing-facility detector is configured to detect a crossing facility provided on the road. The image position determiner is configured to determine, on the basis of a position of the crossing facility, whether or not a display position of the image is included in a no-crossing region near the crossing facility. The illumination controller is configured to control display operation of the light illuminator, to prompt the pedestrian to cross along the crossing facility, on the condition that the image position determiner determines that the display position of the image is included in the no-crossing region.
