Abstract
A display device, including a scanning device, displays an image on a display region using a light ray which scans. The display device includes a light source unit, a scanning control unit, and an emission control unit. The scanning device includes an auxiliary scanning unit which changes an inclination angle of a reflective mirror unit including a reflective mirror and a main scanning unit. The display region includes a plurality of elemental regions coupled to one another. The scanning control unit provides control so that the light ray scans over one of the plurality of elemental regions by changing the inclination angle of the reflective mirror while maintaining the inclination angle of the reflective mirror unit, and control so that the plurality of elemental regions are changed over by changing the inclination angle of the reflective mirror unit.
