PROBLEM TO BE SOLVED: To provide a dimmer in which the occurrence of problems related to color tones is prevented.SOLUTION: A dimmer 10 includes: a first polarizer 20; a second polarizer 22 disposed separately from the first polarizer; and a first pattern phase difference film 30a and a second pattern phase difference film 30b that are disposed between the first polarizer and the second polarizer and having a plurality of slow axis directions in an identical plane. A predetermined relation is satisfied by, in the first pattern phase difference film and the second pattern phase difference film: an in-plane retardation value measured at a wavelength of 450 nm; an in-plane retardation value measured at a wavelength of 550 nm; and an in-plane retardation value measured at a wavelength of 650 nm.SELECTED DRAWING: Figure 1
【課題】色味に関する問題の発生が抑制された調光装置を提供する。【解決手段】第１の偏光子２０と、第１の偏光子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、同一面内に複数の遅相軸方向を有する、第１のパターン位相差膜３０ａおよび第２のパターン位相差膜３０ｂとを備えた調光装置１０であって、第１のパターン位相差膜および第２のパターン位相差膜における、波長４５０ｎｍで測定した面内レタデーション値と、波長５５０ｎｍで測定した面内レタデーション値と、波長６５０ｎｍで測定した面内レタデーション値とが所定の関係を満たす調光装置。【選択図】図１
