Title (EN) OPTICAL LAMINATE AND SURFACE LIGHT SOURCE DEVICE
(FR) STRATIFIÉ OPTIQUE ET DISPOSITIF DE SOURCE DE LUMIÈRE DE SURFACE
(JA) 光学積層体及び面光源装置
Abstract:
(EN) An optical laminate which is provided with: a base layer; a first adhesive layer that is arranged on one surface of the base layer; and a second adhesive layer that is arranged on a surface of the first adhesive layer, said surface being on the reverse side of the surface on which the base layer is. The second adhesive layer contains particles that are capable of scattering light, and the refractive index (n1) of the first adhesive layer and the refractive index (n2) of the second adhesive layer satisfy the following conditions: 1.40 ≤ n1 ≤ 1.50; 1.47 ≤ n2 ≤ 1.85; and 0 < n2 - n1 ≤ 0.45.
(FR) L’invention porte sur un stratifié optique qui comporte : une couche de base ; une première couche adhésive qui est disposée sur une surface de la couche de base ; et une seconde couche adhésive qui est disposée sur une surface de la première couche adhésive, ladite surface étant sur le côté inverse de la surface sur laquelle est la couche de base. La seconde couche adhésive contient des particules qui sont aptes à une diffusion de lumière, et l’indice de réfraction (n1) de la première couche adhésive et l’indice de réfraction (n2) de la seconde couche adhésive satisfont les conditions suivantes : 1,40 ≤ n1 ≤ 1,5 ; 1,47 ≤ n2 ≤ 1,85 ; et 0 < n2 - n1 ≤ 0,45.
(JA)  基材層と、前記基材層の一方の面に設けられた第一粘着層と、前記第一粘着層の前記基材層とは反対側の面に設けられた第二粘着層とを備え、前記第二粘着層が、光を散乱させうる粒子を含み、前記第一粘着層の屈折率n1及び前記第二粘着層の屈折率n2が、 1.40≦n1≦1.50、 1.47≦n2≦1.85、及び、 0<n2-n1≦0.45 を満たす、光学積層体。
