Abstract
(EN)
The present invention addresses the problem of providing: a projection image displaying member with which a projection image can be displayed using p-polarization, and which can achieve a head-up display system having excellent adaptability for polarized sunglasses; a windshield; and a head-up display system. The problem is solved by a projection image displaying member having a transparent substrate having an in-plane retardation of 5,000 nm or more; and at least one selective reflective layer, wherein the selective reflective layer is positioned closer to an incident side of projection light than the transparent substrate.
(FR)
L'invention a pour objet de fournir un élément pour affichage d'image projetée qui permet d'afficher une lumière projetée au moyen d'une lumière polarisée en p, et qui permet de réaliser un système d’affichage tête haute excellent même en termes de propriétés d'adaptation à des lunettes de soleil polarisées. L'invention a aussi pour objet de fournir un pare-brise et un système d’affichage tête haute. À cet effet, l'invention concerne un élément pour affichage d'image projetée qui possède un substrat transparent de retard dans le plan supérieur ou égal à 5000nm, et au moins une couche de réflexion sélective, laquelle couche de réflexion sélective est positionnée côté incidence d'une lumière de projection par rapport au substrat transparent.
