PROBLEM TO BE SOLVED: To provide a variable electromagnetic wave adjustment method capable of achieving a satisfactory contrast with a small haze in a transmission state and small angle dependency.SOLUTION: The variable electromagnetic wave adjustment method includes a control step in which the density of an aggregate of electromagnetic wave adjustment particles 4 is controlled in a range of 0.008/μmto 0.1/μmwhen observing an electromagnetic wave adjustment layer 8 from a direction perpendicular to the electromagnetic wave adjustment layer, by applying an AD voltage to the electromagnetic wave adjustment layer 8 which includes a suspension containing the electromagnetic wave adjustment particles 4 and dispersion medium 6.SELECTED DRAWING: Figure 2 【課題】透過状態におけるヘイズが小さく、角度依存性が小さく、充分なコントラストが得られる可変式電磁波調整方法の提供。【解決手段】電磁波調整粒子４と分散媒６とを含む懸濁液を含有する電磁波調整層８に交流電圧を印加することにより、電磁波調整層８と直交する方向から電磁波調整層を観察したときに、電磁波調整粒子４の凝集体の密度が０．００８個／μｍ２以上０．１個／μｍ２以下となるように制御する制御工程を含む可変式電磁波調整方法。【選択図】図２
