Title (EN) POLARIZING PLATE
(FR) PLAQUE POLARISANTE
(JA) 偏光板
Abstract:
(EN) Provided is a thin polarizing plate that has excellent durability under high temperatures and high humidity. This polarizing plate comprises a polarizing film and a transparent protective layer that is provided to at least one surface of the polarizing film. The polarizing film and the transparent protective layer are laminated with a first adhesive layer therebetween. The thickness of the polarizing film is 10 μm or less. The total thickness of the transparent protective layer is no more than six times the thickness of the polarizing film. The water vapor permeability of the transparent protective layer is 200 g/m2/24 hr or lower. The bulk water absorption of the first adhesive layer is 10 weight% or lower.
(FR) La présente invention concerne une plaque polarisante mince qui a une excellente durabilité sous des températures élevées et une humidité élevée. La plaque polarisante comprend un film polarisant et une couche protectrice transparente qui est disposée sur au moins une surface du film polarisant. Le film polarisant et la couche protectrice transparente sont stratifiés avec une première couche adhésive entre eux. L'épaisseur du film polarisant est de 10 μm ou moins. L'épaisseur totale de la couche protectrice transparente n'est pas supérieure à six fois l'épaisseur du film polarisant. La perméabilité à la vapeur d'eau de la couche protectrice transparente est de 200 g/m2/24 h ou moins. L'absorption d'eau en masse de la première couche adhésive est de 10 % en poids ou moins.
(JA)  高温高湿下での耐久性に優れる薄型の偏光板を提供する。 本発明の偏光板は、偏光膜と、該偏光膜の少なくとも片面に設けられた透明保護層とを備え、 該偏光膜と該透明保護層が、第1の接着層を介して、積層しており、該偏光膜の厚みが、10μm以下であり、該透明保護層の総厚が、該偏光膜の厚みの6倍以下であり、該透明保護層の透湿度が、200g/m/24hr以下であり、該第1の接着層のバルク吸水率が、10重量%以下である。
