Abstract:
(EN) The present invention provides an optical anisotropic film showing excellent reverse wavelength dispersibility, a circularly polarizing plate, and a display device. The optical anisotropic film according to the present invention is formed from a composition comprising a liquid crystal compound and an infrared-absorbing dye. The optical anisotropic film satisfies the relationship of formula (A), and the absorption at a wavelength of 700-900 nm in the fast axis direction of the optical anisotropic film is higher than the absorption at a wavelength of 700-900 nm in the slow axis direction of the optical anisotropic film. Formula (A): Re(450)/Re(550) < 1 wherein Re(450) denotes the in-plane retardation of the optical anisotropic film at a wavelength of 450 nm, and Re(550) denotes the in-plane retardation of the optical anisotropic film at a wavelength of 550 nm.
(FR) La présente invention concerne un film anisotrope optique présentant une excellente dispersibilité de longueur d'onde inverse, une plaque de polarisation circulaire, et un dispositif d'affichage. Le film anisotrope optique selon la présente invention est constitué d'une composition comprenant un composé de cristaux liquides et un colorant absorbant les infrarouges. Le film anisotrope optique satisfait la relation de formule (A), et l'absorption à une longueur d'onde de 700 à 900 nm dans la direction d'axe rapide du film anisotrope optique est supérieure à l'absorption à une longueur d'onde de 700 à 900 nm dans la direction d'axe lent du film anisotrope optique. Formule (A) : Re(450)/Re(550) < 1 dans laquelle Re(450) représente le retard dans le plan du film anisotrope optique à une longueur d'onde de 450 nm, et Re(550) représente le retard dans le plan du film anisotrope optique à une longueur d'onde de 550 nm.
(JA) 本発明は、優れた逆波長分散性を示す光学異方性膜、円偏光板および表示装置を提供する。本発明の光学異方性膜は、液晶化合物および赤外線吸収色素を含む組成物から形成された光学異方性膜であって、光学異方性膜は式(A)の関係を満たし、光学異方性膜の進相軸の方向での波長700~900nmにおける吸収が、光学異方性膜の遅相軸の方向での波長700~900nmにおける吸収よりも大きい。 式(A) Re(450)/Re(550)<1 Re(450)は波長450nmにおける光学異方性膜の面内レタデーションを表し、Re(550)は波長550nmにおける光学異方性膜の面内レタデーションを表す。
