Abstract

L'invention concerne un dispositif d'affichage (3) qui est pourvu d'une unité d'affichage d'image (13) pour afficher une image sur un panneau (7). Le panneau (7) a, sur une surface avant et/ou une surface arrière, une partie en relief (36) sur laquelle une pluralité d'évidements et de saillies sont formés. La partie en relief (36) a une première partie en relief (39) sur laquelle l'image est affichée par la lumière provenant de l'unité d'affichage d'image (13), et une seconde partie en relief (40) sur laquelle l'image n'est pas affichée par l'unité d'affichage d'image (13). La première partie en relief (39) et la seconde partie en relief (40) ont des formes ayant des degrés de diffusion de lumière différents.
