Title (EN) POLARIZING PLATE
(FR) PLAQUE POLARISANTE
(JA) 偏光板
Abstract:
(EN) This polarizing plate exhibits excellent adhesion between a resin layer and a polarizer, and is suppressed in the occurrence of cracks in the polarizer. A polarizing plate 10 comprises a retardation layer 3 and a polarizer 1; and the retardation layer 3 and the polarizer 1 are laminated with a highly adhesive layer 2 being interposed therebetween. The highly adhesive layer 2 has a storage elastic modulus of from 1.0 × 106 Pa to 1.0 × 107 Pa at 85°C.
(FR) Cette plaque de polarisation présente une excellente adhérence entre une couche de résine et un polariseur, et supprimée lors de l'apparition de fissures dans le polariseur. Une plaque de polarisation 10 comprend une couche de retard 3 et un polariseur 1; et la couche de retard 3 et le polariseur 1 sont stratifiés avec une couche hautement adhésive 2 interposée entre eux. La couche hautement adhésive 2 a un module d'élasticité de stockage de 1,0 × 10 6 Pa à 1,0 × 10 7 Pa à 85° C
(JA) 樹脂層と偏光子との密着性に優れ、さらに、偏光子へのクラックの発生を抑制する。偏光板10は、位相差層3と偏光子1とを有し、位相差層3と偏光子1とは易接着層2を介して積層されており、易接着層2の85℃での貯蔵弾性率が1.0×10Pa~1.0×10Paである。
