Abstract | PROBLEM TO BE SOLVED: To provide a polarized light separation film that can reduce a change of color due to a difference in a viewing direction.SOLUTION: A polarized light separation film comprises: a first cholesteric liquid crystal layer 12 that has a cholesteric liquid crystal structure; and a second cholesteric liquid crystal layer 13 that is laminated on the first cholesteric liquid crystal layer and has a cholesteric liquid crystal structure. The center wavelength of selective reflection of the second cholesteric liquid crystal layer is larger than the center wavelength of selective reflection of the first cholesteric liquid crystal layer.SELECTED DRAWING: Figure 1
【課題】見る方向の違いによる色の変化を抑制することができる偏光分離フィルムを提供する。【解決手段】コレステリック液晶構造を具備する第1コレステリック液晶層12と、第1コレステリック液晶層に積層され、コレステリック液晶構造を具備する第2コレステリック液晶層13と、を備え、第2コレステリック液晶層の選択反射の中心波長は、第1コレステリック液晶層の選択反射の中心波長より大きい。【選択図】図1 |
