(FR) ÉLÉMENT OPTIQUE, ÉLÉMENT DE POLARISATION ET DISPOSITIF D'AFFICHAGE
Abstract:
(EN) An optical member, a polarization member, and a display device are provided. The optical member includes a substrate, and a functional layer provided on the substrate, the functional layer including a high refractive layer and a low refractive layer, wherein the high refractive layer has a higher refractive index than that of the substrate and a diffraction grating structure, and the low refractive layer has a lower refractive index than that of the high refractive layer, wherein an interface between the substrate and the high refractive layer and an interface between the high refractive layer and the low refractive layer are in states in which components of the respective layers with the respective interfaces therebetween are compatible with each other.
(FR) La présente invention porte sur un élément optique, un élément de polarisation et un dispositif d'affichage. L'élément optique comprend un substrat et une couche fonctionnelle disposée sur le substrat, la couche fonctionnelle comprenant une couche à indice de réfraction élevé et une couche à faible indice de réfraction, la couche à indice de réfraction élevé ayant un indice de réfraction supérieur à celui du substrat et une structure de réseau de diffraction, et la couche à faible indice de réfraction ayant un indice de réfraction inférieur à celui de la couche à indice de réfraction élevé, une interface entre le substrat et la couche à indice de réfraction élevé et une interface entre la couche à indice de réfraction élevé et la couche à faible indice de réfraction étant dans des états dans lesquels des composants des couches respectives, comportant les interfaces respectives entre elles, sont compatibles les uns avec les autres.
