Abstract:
(EN) Provided is a polarizing plate that has an optical compensation layer, that attains an excellent reflection hue and a view angle property, and that possesses a superior mechanical strength. The polarizing plate that has an optical compensation layer according to the present invention is used in organic EL panels and is equipped with a polarizer, an optically anisotropic layer, a first optical compensation layer, and a second optical compensation layer disposed in this order. The optically anisotropic layer exhibits a refractive index property of nx≥ny>nz, and has an Re(550) of 0-20 nm and an Rth(550) of 5-100 nm. The first optical compensation layer exhibits a refractive index property of nx>ny≥nz, and satisfies the relationship of Re(450)nx≥ny. A laminate made of the first and second optical compensation layers has an Re(550) of 120-160 nm and an Rth(550) of -50 to 80 nm.
(FR) L’invention fournit une plaque de polarisation avec couches de compensation optique permettant de mettre en pratique d’excellentes caractéristiques de teinte de réflexion et d’angle de vision, et possédant une excellente résistance mécanique. La plaque de polarisation avec couches de compensation optique de l’invention est mise en œuvre dans un panneau électroluminescent organique, et est équipée dans l’ordre d’un polariseur, d’une couche optiquement anisotrope, d’une première couche de compensation optique et d’une seconde couche de compensation optique. La couche optiquement anisotrope présente des caractéristiques d’indice de réfraction telles quenx≧ny>nz, sa valeur Re(550) est comprise entre 0nm et 20nm, et sa valeur Rth(550) est comprise entre 5nm et 100nm. La première couche de compensation optique présente des caractéristiques d’indice de réfraction telles que nx>ny≧nz, et satisfait la relation Re(450)<Re(550). La seconde couche de compensation optique présente des caractéristiques d’indice de réfraction telles que nz>nx≧ny. la valeur Re(550) d’un stratifié constitué de la première et de la seconde couche de compensation optique, est comprise entre 120nm et 160nm, et sa valeur Rth(550) est comprise entre -50nm et 80nm.
(JA) 優れた反射色相および視野角特性を実現し、かつ、優れた機械的強度を有する光学補償層付偏光板を提供する。本発明の光学補償層付偏光板は、有機ELパネルに用いられ、偏光子と光学異方性層と第1の光学補償層と第2の光学補償層とをこの順に備える。光学異方性層は、nx≧ny>nzの屈折率特性を示し、Re(550)が0nm~20nm、Rth(550)が5nm~100nmである。第1の光学補償層は、nx>ny≧nzの屈折率特性を示し、Re(450)<Re(550)の関係を満たす。第2の光学補償層は、nz>nx≧nyの屈折率特性を示す。第1の光学補償層と第2の光学補償層との積層体のRe(550)は120nm~160nmであり、Rth(550)は-50nm~80nmである。
