Abstract
a. Elément d'affichage à cristal liquide et son procédé de fabrication. b. Il est caractérisé en ce que l'une, au moins, des pellicules d'alignement se compose de deux couches formées par des dépôts obliques, la première couche étant formée en déposant une matière d'alignement suivant un angle d'incidence de 60 à 88 degrés , tandis que la seconde couche a été formée en déposant une matière d'alignement suivant un angle d'incidence de 45 à 75 degrés . c. Concerne, d'une manière générale, les dispositifs d'affichage à cristal liquide.at. A liquid crystal display element and method of making it. b. It is characterized in that at least one of the alignment films consists of two layers formed by oblique deposits, the first layer being formed by depositing an alignment material at an angle of incidence of 60 to 88 degrees, while the second layer was formed by depositing an alignment material at an angle of incidence of 45 to 75 degrees. vs. Generally relates to liquid crystal display devices.
