PROBLEM TO BE SOLVED: To vary the color tone of transmission light variously in a structure in which the transmission light is controlled by shifting plates held facing each other.SOLUTION: A color tone adjusting device 1 includes first and second color tone adjusting plates 2 and 3 held facing each other. The first and second color tone adjusting plates 2 and 3 are formed by laminating transparent plate-shaped members 5A and 5B, linear polarizers 7A and 7B, and retardation layers 16A and 16B including a liquid crystal material. The retardation layers 16A and 16B of the first and second color tone adjusting plates 2 and 3 include first and second regions AA and BB whose slow axis directions are orthogonal to each other. The addition value of the phase difference between the retardation layer 16A of the first color tone adjusting plate 2 and the retardation layer 16B of the second color tone adjusting plate 3 is 120 nm or more and 550 nm or less, and the differential value of the phase difference therebetween is 10 nm or more and 215 nm or less.SELECTED DRAWING: Figure 1 【課題】対向するように保持された板材をシフトさせて透過光を制御する構成において、透過光の色味を種々に変化させることができるようにする。【解決手段】第１及び第２の色味調整用板材２及び３を対向するように保持して形成された色味調整装置１であって、第１及び第２の色味調整用板材２及び３は、透明板状部材５Ａ、５Ｂと、直線偏光板７Ａ、７Ｂと、液晶材料による位相差層１６Ａ、１６Ｂとの積層により形成される。第１及び第２の色味調整用板材２及び３の位相差層１６Ａ、１６Ｂは、遅相軸方向が直交する第１及び第２の領域ＡＡ、ＢＢが設けられ、第１の色味調整用板材２の位相差層１６Ａと、第２の色味調整用板材３の位相差層１６Ｂとで、位相差の加算値が１２０ｎｍ以上５５０ｎｍ以下であり、位相差の差分値が１０ｎｍ以上２１５ｎｍ以下であるようにする。【選択図】図１
