To provide an optical member which can be switched between an opaque state and a reflective state, and which makes it difficult to observe light transmitting through the optical member.SOLUTION: An optical member 10 provided herein comprises a light control unit 20 capable of controlling haze by applying voltage, and a reflective member 40 laminated on the light control unit 20. The reflective member 40 comprises a support body 41, a mirror layer 43 supported by the support body 41, and a light-shielding layer 45 disposed on the mirror layer 43 on a side opposite the light control unit 20 side.SELECTED DRAWING: Figure 3

    【課題】不透明状態と反射状態とを切り替え可能な光学部材において、当該光学部材を透過する光を観察されにくくする。【解決手段】光学部材10は、電圧の印加によりヘイズ値を調節可能な光制御ユニット20と、光制御ユニット20に積層された反射部材40と、を備える。反射部材40は、支持体41と、支持体41に支持されたミラー層43と、ミラー層43の光制御ユニット20の側とは反対側に配置された遮光層45と、を有する。【選択図】図3
