Title (EN) OPTICAL LAMINATE AND IMAGE DISPLAY DEVICE
(FR) STRATIFIÉ OPTIQUE ET DISPOSITIF D'AFFICHAGE D'IMAGE
(JA) 光学積層体および画像表示装置
Abstract:
(EN) Provided is an optical laminate that has an excellent anti-reflective function despite being provided with a substrate having optical anisotropy (also referred to below as an anisotropic substrate). The optical laminate comprises the following in this order: a polarizing plate including a polarizer and a protective layer arranged on at least one side of the polarizer; a first retardation layer; a second retardation layer; a conductive layer; and a substrate. The in-plane retardation Re(550) of the substrate is larger than 0 nm and the angle formed by the slow axis of the substrate and the slow axis of the second retardation layer is either -5° to 5° or 85° to 95°.
(FR) L'invention concerne un stratifié optique qui a une excellente fonction antireflet malgré le fait qu'il comprend un substrat ayant une anisotropie optique (également désigné ci-après comme substrat anisotrope). Le stratifié optique comprend les éléments suivants dans cet ordre : une plaque polarisante comprenant un polariseur et une couche protectrice agencée sur au moins un côté du polariseur ; une première couche de retard ; une seconde couche de retard ; une couche conductrice ; et un substrat. Le retard dans le plan Re(550) du substrat est supérieur à 0 nm et l'angle formé par l'axe lent du substrat et l'axe lent de la seconde couche de retard est soit de -5° à 5° soit de 85° à 95°.
(JA) 光学的に異方性を有する基材(以下、異方性基材ともいう)を備えながらも、反射防止機能に優れる光学積層体を提供すること。 本発明の光学積層体は、偏光子と該偏光子の少なくとも片側に配置された保護層とを含む偏光板と、第1の位相差層と、第2の位相差層と、導電層と、基材とをこの順に有し、該基材の面内位相差Re(550)が0nmより大きく、該基材の遅相軸と該第2の位相差層の遅相軸とのなす角度が、-5°~5°または85°~95°である。
