Abstract

Le problème décrit par la présente invention est de fournir un dispositif d'affichage (1) qui est capable de supprimer l'incidence, sur un capteur de réception de lumière (42), d'une lumière réfléchie qui a été réfléchie par une couche à indice de réfraction élevé (45), et également de fournir un stratifié optique (51) qui est destiné à être utilisé dans le dispositif d'affichage (1). La solution selon la présente invention porte sur un dispositif d'affichage (1) qui comporte une couche à indice de réfraction élevé (42), une première couche de retard (31), une couche de polarisation linéaire (11) et une unité d'affichage (40) dans cet ordre en partant du côté de visionnement. La couche à indice de réfraction élevé (42) a un indice de réfraction de 1,60 ou plus. L'unité d'affichage (40) comporte un élément d'affichage (41) et un capteur de réception de lumière (42). La première couche de retard (31) et la couche de polarisation linéaire (11) sont stratifiées de manière à recouvrir l'élément d'affichage (41) et le capteur de réception de lumière (42).
