Abstract

Cellule ayant un effet de parallaxe réduit. Elle comprend : une couche de cristaux liquides 14, une électrode transparente 12 en contact avec une première face de la couche de cristaux liquides et une partie réfléchissante conductrice 54 ayant une surface 54a formée d'un réseau aléatoire de formations sphériques analogues à des dômes. Application à l'affichage numerique.Cell with reduced parallax effect. It comprises: a liquid crystal layer 14, a transparent electrode 12 in contact with a first face of the liquid crystal layer and a conductive reflective portion 54 having a surface 54a formed by a random array of domed-like spherical formations. Application to digital display.
