調光フィルムの耐久性を向上する。フィルム状の透明な第1基材15を少なくとも有する第1積層体5Uと、フィルム状の透明な第2基材6を少なくとも有する第2積層体と、前記第1積層体5Uと前記第2積層体5Dとの間に挟持された液晶8aと、前記第1積層体5U及び前記第2積層体5Dの少なくとも一方に設けられた透明電極11,16と、を備え、前記透明電極11,16の駆動により前記液晶8aの配向を制御して透過光を制御する調光フィルム1において、前記第1基材15と遅相軸と前記第2基材6の遅相軸とが平行である。
The present invention addresses the problem of improving the durability of a light control film. A light control film 1 includes: a first laminated body 5U at least having a first substrate 15 that has a film shape and that is transparent; a second laminated body at least having a second substrate 6 that has a film shape and that is transparent; a liquid crystal 8a sandwiched between the first laminated body 5U and the second laminated body 5D; and transparent electrodes 11, 16 provided on at least one of the first laminated body 5U and the second laminated body 5D. Transmitted light is controlled by controlling the alignment of the liquid crystal 8a by driving the transparent electrodes 11, 16. The slow axis of the first substrate 15 and the slow axis of the second substrate 6 are parallel to each other.
