DIMMING DEVICE AND DIMMING FILM SET
To provide technology for improving in-plane dimming performance in a dimming device.SOLUTION: A dimming device in accordance with the present invention includes a first dimming plate and a second dimming plate configured to be relatively movable along a first axis. The first dimming plate includes a first polarizing layer having a first transmission axis and a first retardation layer having an in-plane slow axis varying along the first axis or a second axis intersecting the first axis; and the second dimming plate includes a second polarizing layer having a second transmission axis and a second retardation layer having an in-plane slow axis varying along the first axis or the second axis. The first dimming plate and the second dimming plate at least partially oppose to each other. An absolute value of a difference between Re(1) and Re(2) is equal to or lower than a first threshold or less, where Re(1) is a retardation profile of the first dimming plate along the first axis and Re(2) is a retardation profile of the second dimming plate along the first axis.SELECTED DRAWING: Figure 15
【課題】調光装置における面内の調光性能を向上させる技術を提供する。【解決手段】本開示による調光装置は、第１軸に沿って相対的に移動可能に構成された第１の調光板及び第２の調光板を備え、第１の調光板は、第１透過軸を有する第１偏光層と、第１軸または第１軸と交差する第２軸に沿って面内遅相軸が変化する第１位相差層とを含み、第２の調光板は、第２透過軸を有する第２偏光層と、第１軸または第２軸に沿って面内遅相軸が変化する第２位相差層とを含み、第１の調光板と第２の調光板とは、少なくとも部分的に対面し、第１軸に沿った第１の調光板の位相差プロファイルをＲｅ（１）、第１軸に沿った第２の調光板の位相差プロファイルをＲｅ（２）としたとき、Ｒｅ（１）とＲｅ（２）との差の絶対値が第１の閾値以下である。【選択図】図１５
