Abstract
(EN)
Provided is a laminated body which has excellent hardness and folding performance, and which is transparent and has excellent surface smoothness. This laminated body is employed in an image display device, and is provided with a composite base film having a configuration in which a first base film and a second base film are laminated together. The laminated body is characterized in that: at least one of the first base film and the second base film is a polyimide film, a polyamide-imide film, or an aramid film; and no cracking or breaking occurs in the laminated body when a 180° folding test is performed repeatedly 100,000 times in such a way that a gap between two opposing edges of the laminated body is 3 mm.

L'invention porte sur un corps stratifié qui a une excellente dureté et une excellente performance de pliage, et qui est transparent et présente une excellente régularité de surface. Ce corps stratifié est utilisé dans un dispositif d'affichage d'image, et est pourvu d'un film de base composite présentant une configuration dans laquelle un premier film de base et un second film de base sont stratifiés ensemble. Le corps stratifié est caractérisé en ce que : au moins l'un du premier film de base et du second film de base est un film de polyimide, un film de polyamide-imide ou un film d'aramide ; et aucune fissure ou rupture ne se produit dans le corps stratifié lorsqu'un test de pliage à 180° est effectué de manière répétée 100 000 fois de telle sorte qu'un espace entre deux bords opposés du corps stratifié soit de 3 mm.
(JA)
極めて優れた硬度及び折り畳み性能を有するとともに透明性及び表面の平滑性に優れる積層体を提供する。 画像表示装置に用いられ、第一基材フィルムと第二基材フィルムとが積層された構成を有する複合基材フィルムを備えた積層体であって、上記第一基材フィルム及び第二基材フィルムの少なくとも一方は、ポリイミドフィルム、ポリアミドイミドフィルム、又は、アラミドフィルムであり、上記積層体の対向する2つの辺の間隔が3mmとなるよう180°折り畳む試験を10万回繰り返し行った場合に上記積層体に割れ又は破断が生じないことを特徴とする積層体である。
