Abstract
L'invention concerne les dispositifs d'affichage à cristaux liquides. Elle se rapporte à un réflecteur diélectrique sélectif comprenant des couches déposées alternativement de silicium et de silice, leur épaisseur permettant la sélection de la couleur réfléchie préférentiellement. Les couches de silicium sont avantageusement conductrices, et elles sont dopées à cet effet Application aux panneaux d'affichage recevant des signaux vidéo.
