LIGHT CONTROL DEVICE AND LIGHT CONTROL FILM SET
To provide a technique for achieving desired light control performance of a gradation-type light control device while avoiding an increase in size of the device and reduction in light collection area.SOLUTION: A light control device provides transmittance that changes in steps, and comprises a first polarizing film, a second polarizing film, and first and second retardation films disposed between the first and second polarizing films and configured to at least partially face each other. The first retardation film comprises a plurality of first light control areas that change the in-plane slow axis in steps along a first axis, and the second retardation film comprises a plurality of second light control areas that correspond to the first light control areas and change the in-plane slow axis in steps along the first axis. At least either of the first and second retardation films is configured to be movable to allow for changing areas that face each other.SELECTED DRAWING: Figure 12
【課題】調光装置の大型化または採光面積の縮小を避けつつ、階調タイプの調光装置において所望の調光性能を得る技術を提供する。【解決手段】透過率が段階的に変化する調光装置であって、第１偏光フィルムと、第２偏光フィルムと、第１偏光フィルムと第２偏光フィルムの間に配置され、互いに少なくとも部分的に対面するように構成された第１位相差フィルムおよび第２位相差フィルムと、を有し、第１位相差フィルムは、第１軸に沿って面内遅相軸が段階的に変化する複数の第１調光領域を有し、第２位相差フィルムは、第１調光領域に対応し、かつ、第１軸に沿って面内遅相軸が段階的に変化する複数の第２調光領域を有し、第１位相差フィルムおよび第２位相差フィルムの少なくとも一方は、対面する領域が変化するように可動である調光装置が提供される。【選択図】図１２
