DIMMING FILM AND LAMINATED GLASS
To provide a dimming film that can effectively avoid reduction in the external appearance quality of a product and can be sufficiently stably driven even when the film is used as an intermediate material of a laminated glass and that can effectively avoid reduction in the transmittance and degradation in the aligning property of a liquid crystal so as to prevent visibility of diffracted light.SOLUTION: A laminated glass 1 has a dimming film 10 held between first and second sheet glasses 2, 3 via intermediate layers 4, 5, and has a curved shape. The dimming film includes a liquid crystal layer 14 held between first and second laminates 13, 12, and a spacer 24, in which the first and second laminates have flexible substrates 21A, 21B and electrodes 22A, 22B formed on the substrates, in which a transmissive state and a light-shielding state are switched by controlling alignment of liquid crystal molecules 14A driven by the electrodes. The spacer is a bead spacer having a diameter of 1 to 20 μm and has an occupancy rate of 0.1% or more and 10% or less, and at least one spacer is present within a 200 μm radius range from any point in a dimming region.SELECTED DRAWING: Figure 1
【課題】合わせガラスの中間材に利用する場合等においても、外観品位の低下を有効に回避して十分に安定に駆動することができ、また透過率の低下、液晶の配向性の低下を有効に回避して回折光が見て取られたりすることが無いようにする。【解決手段】合わせガラス１は、中間層４、５を介して第１及び第２の板ガラス２、３により調光フィルム１０を挟持し、曲面形状を有し、調光フィルムは、第１及び第２の積層体１３、１２により挟持された液晶層１４と、スペーサー２４とを備え、第１及び第２の積層体は、可撓性を有する基材２１Ａ，Ｂと、基材に形成された電極２２Ａ，Ｂとを有し、電極による駆動により液晶分子１４Ａの配向を制御して透過状態と遮光状態とを切り替え、スペーサーは、直径１〜２０μｍのビーズスペーサーであり、占有率が０．１％以上１０％以下であり、調光領域内の任意の点から半径２００μｍの範囲において少なくとも１つ存在する。【選択図】図１
