ABSTRACT:
A display device has plural light emitting elements disposed in line, a first optical system to diverge light emitted from the light emitting elements, and a second optical system to converge the light passing through the first optical system. The first optical system is rotatable by a rotating unit which a control unit controls. The control unit also controls lighting-on and lighting-off of the light emitting elements in sync with rotary movement of the first optical system and according to image information to be displayed, thereby the second optical system converging the light to produce the image information.
