DIMMER
PROBLEM TO BE SOLVED: To provide a dimmer having a great number of gradations and capable of controlling light with multiple gradations.SOLUTION: A dimmer 10 comprises a light control part 12 and a movement part 14. The light control part 12 includes: a first polarizer 20; a second polarizer 22 disposed separately from the first polarizer 20; and three or more pattern phase difference films 30a, 30b, 30c disposed between the first polarizer and the second polarizer and having a plurality of slow axis directions in an identical plane. The first polarizer, the second polarizer, and each of the pattern phase difference films are disposed to be parallel to each other. The movement part moves at least one of the three or more pattern phase difference films relative to the pattern phase difference films in a parallel manner. At least two of the three or more pattern phase difference films have different retardation values. At least one of the three or more pattern phase difference film is relatively moved in parallel manner by the movement part, and thereby, the transmissivity of incident light, incident from the first polarizer or the second polarizer, is changed.SELECTED DRAWING: Figure 1
【課題】階調数が多く多階調の調光ができる調光装置を提供する。【解決手段】調光装置１０は、第１の偏光子２０と、第１の偏光子２０と離間して配置された第２の偏光子２２と、第１の偏光子と第２の偏光子の間に配置された３枚以上の、同一面内に複数の遅相軸方向を有するパターン位相差膜３０ａ，３０ｂ，３０ｃとを備え、第１の偏光子、第２の偏光子および各パターン位相差膜は互いに平行に配置されている調光部１２と、３枚以上のパターン位相差膜のうち、少なくとも１枚をパターン位相差膜に対して相対的に平行に移動させる移動部１４とを有する。３枚以上のパターン位相差膜のうち、少なくとも２枚のパターン位相差膜はレタデーションの値が異なる。移動部により、３枚以上のパターン位相差膜のうち、少なくとも１枚のパターン位相差膜を相対的に平行に移動させることで、第１の偏光子または第２の偏光子から入射される入射光の透過率を変える。【選択図】図１
