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
