Abstract
(EN) Provided are a layered body and a display device including the same, the layered body including a substrate layer and a resin layer disposed on at least one surface of the substrate layer. The resin layer contains a light scattering agent (A). When the surface tension of the substrate layer is defined as σs (mN/m) and the surface tension of the resin layer is defined as σr (mN/m), formula |σs-σr|≤11.0 is satisfied.
(FR) L'invention concerne un corps stratifié et un dispositif d'affichage le comprenant, le corps stratifié comprenant une couche de substrat et une couche de résine disposée sur au moins une surface de la couche de substrat. La couche de résine contient un agent de diffusion de lumière (A). Lorsque la tension de surface de la couche de substrat est définie comme σs (mN/m) et la tension de surface de la couche de résine est définie comme σr (mN/m), la formule |σs-σr|≤11,0 est satisfaite.
(JA) 基材層とその少なくとも一方の表面上に配置される樹脂層とを含み、樹脂層は光散乱剤(A)を含み、基材層の表面張力をσs(mN/m)、樹脂層の表面張力をσr(mN/m)とするとき、次式:|σs-σr|≦11.0を満たす積層体及びこれを含む表示装置が提供される。
