Abstract
A display device includes a light source, a first optical system, a first mirror, a changing element, and a second optical system. The light source emits a light beam. The first optical system converts the light beam emitted from the light source into a collimated light beam. The first mirror reflects the light beam coming through the first optical system while rotating around a first axis. The changing element changes a traveling direction of the light beam reflected by the first mirror. The second optical system deflects the light beam coming through the changing element. The changing element changes the traveling direction of the light beam such that an angle of the light beam in the traveling direction which has been reflected by the first mirror is changed more greatly in a peripheral section than in a central section.
