Abstract:
(EN) The purpose of the present invention is to provide a laminate for a flexible image display device in which as a result of using an optical film, which includes at least a polarizing film, and a pressure-sensitive adhesive layer having a specific modulus, excellent bending resistance and adhesion are demonstrated without the occurrence of peeling or cracking in repeated bending at ordinary temperature and even under a high-temperature environment, and also to provide a flexible image display device on which the laminate for a flexible image display device is arranged. The laminate for a flexible image display device including a pressure-sensitive adhesive layer and an optical film including at least a polarizing film is characterized in that a stress at a 100% modulus of the pressure-sensitive adhesive layer is 0.01-0.1 N/mm2, and that a stress at a 500% modulus of the pressure-sensitive adhesive layer is 0.05-0.2 N/mm2.
(FR) La présente invention a pour objet de fournir un stratifié destiné à un dispositif d'affichage d'image flexible dans lequel, suite à l'utilisation d'un film optique, qui comprend au moins un film polarisant, et une couche adhésive sensible à la pression comprenant un module spécifique, une excellente résistance à la flexion et une excellente adhérence sont mises en évidence sans l'apparition de décollement ou de fissuration lors d'une flexion répétée à température ordinaire et même dans un environnement à haute température, et également de fournir un dispositif d'affichage d'image flexible sur lequel le stratifié destiné à un dispositif d'affichage d'image flexible est disposé. Le stratifié destiné à un dispositif d'affichage d'image flexible comprenant une couche adhésive sensible à la pression et un film optique comprenant au moins un film polarisant est caractérisé en ce qu'une contrainte à un module de 100 % de la couche adhésive sensible à la pression est comprise entre 0,01 et 0,1 N/mm2, et qu'une contrainte à un module de 500 % de la couche adhésive sensible à la pression est comprise entre 0,05 et 0,2 N/mm2.
(JA) 本発明は、少なくとも偏光膜を含む光学フィルムと、特定のモジュラスを有する粘着剤層を用いることで、常温や高温環境下に曝された場合であっても、繰り返しの屈曲に対しても剥がれや割れが生じることがなく、耐屈曲性や密着性に優れたフレキシブル画像表示装置用積層体、及び、前記フレキシブル画像表示装置用積層体が配置されたフレキシブル画像表示装置を提供することを目的とする。粘着剤層と、少なくとも偏光膜を含む光学フィルムと、を含むフレキシブル画像表示装置用積層体であって、前記粘着剤層の100%モジュラスの応力が、0.01~0.1N/mmであり、かつ、前記粘着剤層の500%モジュラスの応力が、0.05~0.2N/mmであることを特徴とするフレキシブル画像表示装置用積層体。
