Title (EN) LONG OPTICAL LAYERED BODY AND IMAGE DISPLAY DEVICE
(FR) CORPS STRATIFIÉ OPTIQUE LONG ET DISPOSITIF D'AFFICHAGE D'IMAGE
(JA) 長尺状の光学積層体および画像表示装置
Abstract:
(EN) Provided is a long optical layered body whereby variation in display characteristics between each product can be reduced when the long optical layered body is cut to a predetermined size and applied in an image display device. This optical layered body is long, and has a polarizing plate including a polarizer and a protective layer on at least one side of the polarizer, a first phase difference layer, a second phase difference layer, an electroconductive layer, and a substrate adhesively layered on the electroconductive layer, in this order. The in-plane phase difference Re (550) of the substrate is 3 nm to 6 nm, the phase difference variation in the width direction is 10% to 30%, and the slow-axis direction variation in the width direction is 1° to 5°. The in-plane phase difference Re (550) of the first phase difference layer is 220 nm to 250 nm, the angle formed by the slow axis of the first phase difference layer and the absorption axis of the polarizer is 10° to 20°, the in-plane phase difference Re (550) of the second phase difference layer is 110 nm to 125 nm, and the angle formed by the slow axis of the second phase difference layer and the absorption axis of the polarizer is 65° to 85°.
(FR) L'invention concerne un corps stratifié optique long grâce auquel une variation dans des caractéristiques d'affichage entre chaque produit peut être réduite lorsque le corps stratifié optique long est découpé à une dimension prédéterminée et appliqué dans un dispositif d'affichage d'image. Le corps stratifié optique est long, et a une plaque de polarisation comprenant un polariseur et une couche protectrice sur au moins un côté du polariseur, une première couche à différence de phase, une seconde couche à différence de phase, une couche électroconductrice, et un substrat stratifié de façon adhésive sur la couche électroconductrice, dans cet ordre. La différence de phase dans le plan Re (550) du substrat est de 3 nm à 6 nm, la variation de différence de phase dans la direction de la largeur est de 10 % à 30 %, et la variation de direction d'axe lent dans la direction de la largeur est de 1° à 5°. La différence de phase dans le plan Re (550) de la première couche à différence de phase est de 220 nm à 250 nm, l'angle formé par l'axe lent de la première couche à différence de phase et l'axe d'absorption du polariseur est de 10° à 20°, la différence de phase dans le plan Re (550) de la seconde couche à différence de phase est de 110 nm à 125 nm, et l'angle formé par l'axe lent de la seconde couche à différence de phase et l'axe d'absorption du polariseur est de 65° à 85°.
(JA) 所定サイズに裁断して画像表示装置に適用した場合に製品ごとの表示特性のばらつきを小さくすることができる長尺状の光学積層体を提供する。本発明の光学積層体は、長尺状であり、偏光子と偏光子の少なくとも一方の側に保護層とを含む偏光板と、第1の位相差層と、第2の位相差層と、導電層と、導電層に密着積層された基材と、をこの順に有する。基材の面内位相差Re(550)は3nm~6nmであり、幅方向における位相差のばらつきは10%~30%であり、幅方向における遅相軸方向のばらつきは1°~5°である。第1の位相差層の面内位相差Re(550)は220nm~250nmであり、第1の位相差層の遅相軸と偏光子の吸収軸とのなす角度は10°~20°であり、第2の位相差層の面内位相差Re(550)は110nm~125nmであり、第2の位相差層の遅相軸と偏光子の吸収軸とのなす角度は65°~85°である。
