Abstract

La présente invention concerne un dispositif de sécurité comprenant un substrat transparent (1) pourvu d'une structure de surface prismatique (2) qui définit un réseau de facettes sensiblement planes. Une couche d'adhésif (3) s'étend autour du périmètre d'une surface du substrat (1) de sorte que ce dispositif de sécurité puisse être collé à un autre substrat, au moins quelques parties de cette surface étant exposées à l'air, ces parties étant espacées de l'autre substrat en utilisation afin de définir un substrat transparent et/ou une interface air de sorte que les parties correspondant à la structure de surface prismatique (2) forment un réflecteur du fait de la réflexion interne totale lorsqu'elles sont vues selon au moins un premier angle de vision et sont transparentes lorsqu'elles sont visionnées selon au moins un second angle de vue.
