Abstract

L'invention concerne un dispositif d'affichage à cristal liquide. Dans ce dispositif comportant deux plaques de support 1, 2 et un cadre 3 les enserrant et limitant une couche de cristal liquide 11, à partir de la première plaque de support 2 ou 1, au niveau de la surface résiduelle, s'étendent des entretoises 9 qui prennent appui sur des parties saillantes (parties d'entretoisement 7, 12) de la première plaque de support 2 ou 1. Application notamment aux systèmes d'affichage numérique.
