PROBLEM TO BE SOLVED: To provide a structure for video projection that prevents the occurrence of peeling between a reflection layer and a second transparent resin layer.SOLUTION: A structure for video projection comprises: a first transparent layer 143 that has a rugged surface; a reflection layer 145 that is installed on the rugged surface of the first transparent layer 143; and an upper layer 160 that is arranged on the reflection layer 145. The upper layer 160 is formed of a polymer having a mold shrinkage factor of less than 3%; the upper layer 160 has a water absorption of less than 1%.SELECTED DRAWING: Figure 2 【課題】反射層と第２の透明樹脂層の間で剥離が生じ難い、映像投影用構造体を提供する。【解決手段】凹凸表面を有する第１の透明層１４３と、該第１の透明層１４３の前記凹凸表面に設置された反射層１４５と、該反射層１４５の上に配置された上部層１６０と、を有し、前記上部層１６０は、成形収縮率が３％未満である重合体で構成され、前記上部層１６０は、吸水率が１％未満である、映像投影用構造体。【選択図】図２
