Title (EN) POLARIZING PLATE WITH RETARDATION LAYER AND IMAGE DISPLAY DEVICE
(FR) PLAQUE DE POLARISATION À COUCHE À COUCHE DE RETARD ET DISPOSITIF D'AFFICHAGE D'IMAGE
(JA) 位相差層付偏光板および画像表示装置
Abstract:
(EN) Provided is a polarizing plate with a retardation layer, which has excellent durability and weather resistance, and which enables the achievement of an image display device that has excellent hue. A polarizing plate with a retardation layer according to the present invention sequentially comprises a polarizing plate that has a protective layer and a polarizer, a retardation layer, and an adhesive layer in this order. The light transmittance of the protective layer at a wavelength of 380 nm is 10% or less; the light transmittance of the polarizing plate at a wavelength of 380 nm is 5% or less; the light transmittance of the adhesive layer at a wavelength of 405 nm is 5% or less; and the light transmittance of the polarizing plate with a retardation layer at a wavelength of 405 nm is 3% or less.
(FR) L'invention concerne une plaque de polarisation ayant une couche de retard, qui a une excellente durabilité et une excellente résistance aux intempéries, et qui permet la réalisation d'un dispositif d'affichage d'image qui a une excellente teinte. Une plaque de polarisation ayant une couche de retard selon la présente invention comprend séquentiellement une plaque de polarisation qui a une couche de protection et un polariseur, une couche de retard et une couche adhésive dans cet ordre. La transmittance de lumière de la couche de protection à une longueur d'onde de 380 nm est de 10 % ou moins ; la transmittance de lumière de la plaque de polarisation à une longueur d'onde de 380 nm est de 5 % ou moins ; la transmittance de lumière de la couche adhésive à une longueur d'onde de 405 nm est de 5 % ou moins ; et la transmittance de lumière de la plaque de polarisation ayant une couche de retard à une longueur d'onde de 405 nm est de 3 % ou moins.
(JA) 優れた耐久性および耐候性を有し、かつ、優れた色相を有する画像表示装置を実現し得る位相差層付偏光板が提供される。本発明の位相差層付偏光板は、保護層および偏光子を有する偏光板と、位相差層と、粘着剤層と、をこの順に有する。保護層の波長380nmの光線透過率は10%以下であり、偏光板の波長380nmの光線透過率は5%以下であり、粘着剤層の波長405nmの光線透過率は5%以下であり、位相差層付偏光板の波長405nmの光線透過率は3%以下である。
