Abstract
(EN)
A wide view film (light diffusing member) comprises: a translucent base material; a plurality of light-shielding layers scattered on one side of the base material; and a transparent resin layer (translucent material layer) provided on the one side of the base material. At least some of the plurality of light-shielding layers have a planar shape enclosed by a first figure and a second figure included in the first figure, or have a planar shape enclosed by at least a part of the first figure and at least a part of the second figure overlapping with the first figure. A hollow part is provided in the light-shielding layer forming region. The cross-sectional area of the hollow part formed by cutting the hollow part parallel to the one side of the base material is large on the light-shielding layer side and gradually becomes smaller as the distance from the light-shielding layer increases. The part other than the hollow part is set to be the translucent part.

L'invention concerne un film grand-angle (élément de diffusion de lumière) qui comprend : un matériau de base translucide ; une pluralité de couches de protection contre la lumière dispersées sur un côté du matériau de base ; et une couche de résine transparente (couche de matériau translucide) disposée sur ledit côté du matériau de base. Au moins certaines de la pluralité de couches de protection contre la lumière ont une forme plane renfermée par une première figure et une seconde figure incluse dans la première figure, ou ont une forme plane renfermée par au moins une partie de la première figure et au moins une partie de la seconde figure se chevauchant avec la première figure. Une partie creuse est ménagée dans la région de formation de couche de protection contre la lumière. La zone en coupe transversale de la partie creuse formée par coupe de la partie creuse parallèle audit côté du matériau de base est grande sur le côté couche de protection contre la lumière et devient progressivement plus petite au fur et à mesure que la distance à partir de la couche de protection contre la lumière augmente. La partie autre que la partie creuse est configurée pour être la partie translucide.

 視野角拡大フィルム(光拡散部材)は、光透過性を有する基材と、基材の一面に点在する複数の遮光層と、基材の一面に設けられた透明樹脂層(光透過性材料層)と、を備える。複数の遮光層のうちの少なくとも一部の遮光層は、第1の図形と第1の図形に内包される第2の図形とによって囲まれた平面形状、もしくは、第1の図形の少なくとも一部と第1の図形に重なる第2の図形の少なくとも一部とによって囲まれた平面形状を有し、遮光層の形成領域に、基材の一面に平行な平面で切断したときの断面積が遮光層側で大きく、遮光層から離れるにつれて漸次小さくなる中空部が設けられ、中空部以外の部分が光透過部とされている。
