Abstract

L'invention concerne une feuille de réflexion à grand angle d'observation pouvant régler la direction de la lumière efficacement réfléchie selon une étendue angulaire d'observation spécifique, tout en maintenant les caractéristiques de grand angle d'observation. Cette feuille fournit une réflexion lumineuse et son utilisation est particulièrement appropriée en tant qu'élément constitutif d'une feuille d'affichage d'images.
