Abstract
L'invention concerne les dispositifs d'affichage pour télévision qui permettent notamment une projection sur grand écran. Elle consiste à réaliser une cellule à cristal liquide inscriptible par une méthode thermo-optique et à munir cette cellule d'un système d'inscription comprenant des lignes chauffantes permettant de procéder à une inscription ligne par ligne. Elle permet de réaliser par des méthodes de fabrication des circuits intégrés, un dispositif de projection de télévision sur grand écran entièrement statique.
