Abstract

La présente invention concerne un dispositif d'affichage qui est monté sur un tableau de bord d'un véhicule et qui a une section de dispositif d'affichage et une section à miroir concave. La section de dispositif d'affichage a au moins un corps d'affichage pour afficher des informations concernant la carrosserie du véhicule dans une zone d'affichage qui a une forme sensiblement rectangulaire selon une vue en plan. La section à miroir concave est placée à l'avant du véhicule de sorte à faire face à la section de dispositif d'affichage et elle réfléchit la lumière, qui est affichée dans la zone d'affichage, pour faire afficher la lumière réfléchie sous une forme agrandie pour un occupant du véhicule. Le miroir concave et le corps d'affichage sont disposés de telle sorte que le corps d'affichage est arrondi dans la direction longitudinale de la zone d'affichage de sorte à correspondre à la forme de la surface de réflexion du miroir concave et le centre de courbure du miroir concave se trouve au centre de courbure du corps d'affichage.
