Abstract

FABRICATION D'UNE CELLULE D'AFFICHAGE ELECTRO-OPTIQUE. LE CRISTAL LIQUIDE EST DISPOSE ENTRE DEUX PLAQUES SUR LESQUELLES EST DEPOSE UN FILM D'ALIGNEMENT FORME DE DEUX DEPOTS DE MATIERE D'ALIGNEMENT SOUS UNE INCIDENCE DE 5, LA PROJECTION SUR LA PLAQUE DU VECTEUR D'APPLICATION D'UN DES DEPOTS FORMANT UN ANGLE DE 180 AVEC LA PROJECTION DU VECTEUR D'APPLICATION DE L'AUTRE DEPOT. LES MOLECULES DU CRISTAL LIQUIDE S'ANCRENT SUR LA PLAQUE SOUS UN ANGLE INFERIEUR A 10, L'ANGLE D'ANCRAGE MOYEN SUR LES DEUX PLAQUES EST INFERIEUR A 5. APPLICATION AUX CELLULES D'AFFICHAGE ELECTRO-OPTIQUE A CRISTAUX.
