PROCEDE DE REALISATION D'UN ECRAN D'AFFICHAGE A MATRICE ACTIVE ET A CONDENSATEURS DE STOCKAGE ET ECRAN OBTENU PAR CE PROCEDE

Le procédé comprend deux niveaux de masquage seulement. Lors du second masquage, on définit des lignes capacitives (LC) (dédiées ou confondues avec les lignes d'adressage) qui chevauchent les pixels pour former les capacités de stockage (Cs). Application à l'affichage sur écrans plats à cristaux liquides. A liquid crystal display screen including a substrate with conductive addressing columns and conductive blocks, each including a block lengthening piece, a layer of semiconductive material followed by a layer of nonconductive material formed on the addressing columns and conductive blocks, and conductive addressing lines formed on the nonconductive material and each overlapping a block lengthening piece. The block lengthening pieces, the conductive addressing columns, and the conductive addressing lines form addressing transistors. Also, capacitive lines are formed on the nonconductive material and overlap the conductive blocks such that the conductive blocks, the semiconductive material, the nonconductive material, and the capacitive lines form storage capacitors.
