Abstract
A light scan device which forces a beam light depending on an image signal to scan, including: a light source part for supplying the beam light; and a scanning part for forcing the beam light from the light source part to scan an illumination-target region in a first direction and a second direction substantially orthogonal to the first direction, wherein the scanning part is driven so that a frequency with which the beam light is forced to scan in the first direction is higher than a frequency with which the beam light is forced to scan in the second direction, and a spot formed on the illumination-target region by the beam light has a form with a shorter size in the first direction than in the second direction.
