To provide a dead angle auxiliary device that can be thinned while improvement in brightness and removal of luminance unevenness are realized.SOLUTION: A dead angle auxiliary device includes a first optical element 11 and a second optical element 20. The first optical element is used so that a first portion of light made incident at a first angle from an outer view is reflected at a plurality of second angles different from each other. The second optical element is disposed at a position opposite to the first optical element and is used so that a plurality of light beams reflected by the first optical element and made incident at the plurality of second angles are reflected at a third angle toward a user.SELECTED DRAWING: Figure 2

    【課題】輝度向上及び輝度ムラの改善を実現しつつ、薄型化が可能な死角補助装置を提供する。【解決手段】死角補助装置は、第1光学素子11と、第2光学素子20と、を備える。第1光学素子は、外景から第1角度で入射した光の1部を互いに異なる複数の第2角度で反射する。第2光学素子は、第1光学素子と対向する位置に配置され、第1光学素子により反射されて複数の第2角度で入射した複数の光を、使用者の方向へ第3角度で反射する。【選択図】図2
