DIMMING DEVICE, LAMINATE FOR DIMMING DEVICE AND DIMMING CELL

To provide a dimming device, a laminate for a dimming device and a dimming cell, which can suppress generation of a Newton ring while suppressing generation of a liquid crystal accumulation as a phenomenon that a large amount of a liquid crystal is locally present.SOLUTION: A dimming device 10 includes a first transparent substrate 11, a second transparent substrate 12, a dimming cell 20 disposed between the first transparent substrate 11 and the second transparent substrate 12, a first intermediate film 13 disposed between the first transparent substrate 11 and the dimming cell 20, a second intermediate film 14 disposed between the second transparent substrate 12 and the dimming cell 20, and a film 33 disposed between the dimming cell 20 and the first intermediate film 13. An air gap layer G is provided between the dimming cell 20 and the film 33, and an antireflection layer 37 is provided at a position facing the air gap layer G.SELECTED DRAWING: Figure 3 【課題】局所的に液晶が多く存在する現象である液晶だまりの発生を抑制しつつ、ニュートンリングの発生を抑制することが可能な、調光装置、調光装置用積層体及び調光セルを提供する。【解決手段】調光装置１０は、第１透明基板１１と、第２透明基板１２と、第１透明基板１１と第２透明基板１２との間に配置された調光セル２０と、第１透明基板１１と調光セル２０との間に配置された第１中間膜１３と、第２透明基板１２と調光セル２０との間に配置された第２中間膜１４と、調光セル２０と第１中間膜１３との間に配置されたフィルム３３と、を備えている。調光セル２０とフィルム３３との間に、空隙層Ｇが設けられ、空隙層Ｇに面する位置に、反射防止層３７が設けられている。【選択図】図３
