Title (EN) OPTICAL FILM
(FR) FILM OPTIQUE
(JA) 光学フィルム
Abstract:
(EN) In order to provide an optical film which, by exhibiting a high absorption selectivity for UV light and for short-wavelength visible light near the wavelength 405nm, has a good deterioration suppression function for suppressing deterioration of a phase-difference film or an organic EL light-emitting element due to UV light and short-wave visible light, this optical film includes a selective light absorption layer A satisfying formula (1) below and a selective light absorption layer B satisfying formula (2) below. (1) A(350) ≥ 0.5 (2) A(405) ≥ 0.5 [In formula (1), A(350) represents absorbance at the wavelength 350 nm. In formula (2), A(405) represents absorbance at the wavelength 405 nm.]
(FR) Afin de fournir un film optique qui, en présentant une sélectivité d'absorption élevée pour la lumière UV et pour une lumière visible de courte longueur d'onde proche de la longueur d'onde 405 nm, a une bonne fonction de suppression de détérioration pour supprimer la détérioration d'un film à différence de phase ou d'un élément électroluminescent EL organique en raison de la lumière ultraviolette et de la lumière visible à ondes courtes, le film optique selon l'invention comprend une couche d'absorption de lumière sélective A satisfaisant à la formule (1) ci-dessous et une couche d'absorption de lumière sélective B satisfaisant la formule (2) ci-dessous. (1) A(350) ≥ 0,5 (2) A(405) ≥ 0,5 [Dans la formule (1), A(350) représente l'absorbance à la longueur d'onde de 350 nm. Dans la formule (2), A(405) représente l'absorbance à la longueur d'onde 405 nm.]
(JA) 紫外線及び波長405nm付近の短波長の可視光に対する高い吸収選択性を示すことにより、位相差フィルム又は有機EL発光素子の紫外線及び短波長の可視光による劣化について良好な抑制機能を有する光学フィルムを提供する。 下記式(1)を満たす光選択吸収層A及び下記式(2)を満たす光選択吸収層Bを含む光学フィルム。 A(350)≧0.5 (1) A(405)≧0.5 (2) [式(1)中、A(350)は、波長350nmにおける吸光度を表す。 式(2)中、A(405)は波長405nmにおける吸光度を表す。]
