The light control sheet 100 comprises: a light control layer 10 having a plurality of light control parts 11 that control light and a light transmission part 16 that transmits light arranged at least between the light control parts 11; and a protective film 40 arranged at a back face side of the light control layer 10. The light control part 11 is arranged along a prescribed direction, in-plane of the light control sheet 100. The light control part 11 exhibits different effects with regard to light applied from a front face side and light applied from the back face side. The protective film 40 has a mark for indicating the front face side or the back face side. |
