A method of manufacturing a display device comprising a substrate (1) having barrier ribs (9). The method provides a pattern of barrier ribs (9) of frit material (5) by moving a squeegee (7) relative to a substrate (1). The barrier ribs (9) extend in a longitudinal direction and have a predefined profile (11) in a cross-section which is perpendicular to the longitudinal direction. A contact portion (13) of the squeegee (7) comprises a profile (15) for defining the predefined profile (11). The profile (15) has a groove structure comprising grooves (17) in a cross-section corresponding to the predefined profile (11) in the cross-section of the barrier ribs (9). L'invention concerne un procédé de fabrication d'un dispositif d'affichage comprenant un substrat (1) doté de nervures protectrices (9). Ce procédé comporte un motif de nervures (9) en matériau fritté (5) et consiste à déplacer une raclette (7) par rapport au substrat (1). Les nervures (9) s'étendent dans le sens longitudinal et possèdent un profil déterminé (11) dont la section est perpendiculaire au sens longitudinal. Une portion de contact (13) de la raclette (7) comprend un profil (15) servant à définir le profil déterminé (11). Ce profil (15) comporte une structure de gorges (17) ménagées pour que leur section corresponde au profil déterminé (11) de la section des nervures (9).
