Abstract

Abstract Translated from French Ecran d'affichage à matrice active sans transistor parasite et procédé de fabrication. Deux appendices (53, 57) reliés à une colonne et un pavé constituent, le premier, la source et, le second, le drain d'un transistor en couches minces. La forme particulière de l'appendice (57) relié à la colonne évite l'apparition d'un transistor parasite avec la colonne suivante. Active matrix display screen without parasitic transistor and manufacturing method. Two appendages (53, 57) connected to a column and a block constitute, the first, the source and, the second, the drain of a thin film transistor. The particular shape of the appendage (57) connected to the column prevents the appearance of a parasitic transistor with the next column.
