Title (EN) POLARIZING PLATE
(FR) PLAQUE DE POLARISATION
(JA) 偏光板
Abstract:
(EN) [Problem] One purpose of the present invention is to provide a polarizing plate which is suppressed in warping caused by shrinkage of a polarizer and a reflective polarizing plate. Another purpose of the present invention is to provide, for example, a polarizing plate which is also suppressed in cohesive failure of an adhesive that is applied to a glass panel of a liquid crystal cell. [Solution] A polarizing plate which is obtained by sequentially laminating a reflective polarizing plate, a first adhesive layer, a polarizer, a protective film and a second adhesive layer in this order, and wherein: the interlayer thickness from the first adhesive layer-side surface of the reflective polarizing plate t o a surface of the second adhesive layer, said surface being on the reverse side of the protective film-side surface, is 60 μm or less; and the tensile modulus of elasticity of the protective film at 85°C is 2,500 MPa or less.
(FR) Le problème décrit par la présente invention est d'atteindre l'objet qui est de fournir une plaque de polarisation qui ne présente pas de gauchissement provoqué par le rétrécissement d'un polariseur et d'une plaque de polarisation réfléchissante. Un autre objet de la présente invention est de fournir, par exemple, une plaque de polarisation dans laquelle est supprimée la rupture cohésive d'un adhésif qui est appliqué sur un panneau de verre d'une cellule à cristaux liquides. La solution porte sur une plaque de polarisation qui est obtenue en stratifiant successivement une plaque de polarisation réfléchissante, une première couche adhésive, un polariseur, un film de protection et une seconde couche adhésive dans cet ordre, et dans laquelle : l'épaisseur intermédiaire entre la surface du côté première couche adhésive de la plaque de polarisation réfléchissante et une surface de la seconde couche adhésive, ladite surface étant sur le côté inverse de la surface côté film de protection, est inférieure ou égale à 60 µm; et le module d'élasticité en traction du film de protection à 85 °C est inférieur ou égal à 2 500 MPa.
(JA) [課題]本発明は、偏光子および反射型偏光板の収縮に起因する反りが抑制された偏光板を提供することを目的とする。さらに、本発明は、例えば、液晶セルのガラスパネルに貼合される粘着剤の凝集破壊も抑制された偏光板を提供することを目的とする。 [解決手段]反射型偏光板と、第1の粘着剤層と、偏光子と、保護フィルムと、第2の粘着剤層とがこの順で積層された偏光板であって、前記反射型偏光板における第1の粘着剤層側表面から、前記第2の粘着剤層における前記保護フィルムとは反対側の表面までの層間厚みが、60μm以下であり、前記保護フィルムの85℃における引張弾性率が、2500MPa以下である、偏光板。
