To provide a display unit that displays a virtual image having an appropriate brightness.SOLUTION: A display unit comprises: a light source that radiates light; a light deflection unit that deflects the radiated light to be incident in a main scanning direction and a sub scanning direction; a divergent optical system that diverges deflected light to be incident, and the display unit forms a virtual image to be visually recognized by an observer with divergent light diverged by the divergent optical system. The display unit has a dioptric system refracting the deflected light to be incident on a light path between the light deflection unit and the divergent optical system, and the refractive power in the main scanning direction and the refractive power in the sub scanning direction are different in the dioptric system.SELECTED DRAWING: Figure 13

    【課題】適切な輝度を有する虚像を表示する表示装置を提供する。【解決手段】光を照射する光源と、入射される照射された光を主走査方向および副走査方向に偏向する光偏向部と、入射される偏向された偏向光を発散させる発散光学系と、を有し、発散光学系によって発散された発散光によって観察者に視認させる虚像を形成する表示装置であって、光偏向部と前記発散光学系との間の光路上に、入射される偏向光を屈折させる屈折光学系を有し、屈折光学系の主走査方向の屈折力と副走査方向の屈折力が異なる表示装置である。【選択図】図13
