To provide a transparent screen that can separate a direction in which a hot spot is observed and a direction in which a bright video is observed from each other.SOLUTION: A transparent screen comprises: a first transparent layer; a reflecting layer that reflects light of a projected video; and a second transparent layer that is provided on the opposite side of the first transparent layer with respect to the reflecting layer, and allows visual recognition of a background. When a surface of the first transparent layer on the opposite side of the reflecting layer is a reference surface, the reflecting layer has a plurality of reflecting inclined surfaces inclined in the same direction as that of the reference surface and reflecting the light, and the plurality of reflecting inclined surfaces each have irregularities and are formed in a striped shape when viewed from a normal direction of the reference surface.SELECTED DRAWING: Figure 1

    【課題】ホットスポットが観察される方向と、明るい映像が観察される方向とを分離できる透明スクリーンの提供。【解決手段】第1の透明層と、投影される映像の光を反射する反射層と、前記反射層を基準として前記第1の透明層とは反対側に設けられる第2の透明層とを有し、背景を視認可能な透明スクリーンであって、前記反射層は、前記第1の透明層の前記反射層とは反対側の面を基準面とするとき、前記基準面に対し同じ向きに傾斜し、且つ前記光を反射する反射斜面を複数有し、複数の前記反射斜面は、それぞれ凹凸を有し、前記基準面の法線方向から見たときに縞状に形成される、透明スクリーン。【選択図】図1
