Abstract

L'invention porte sur un écran plasma. Des électrodes d'adresse (12) sont disposées sur le substrat de la surface arrière (2) de l'écran et une couche diélectrique (11) les recouvre. Des cloisonnements longitudinaux (25) sont formées sur la couche diélectrique et les espaces les séparant sont couverts de trois types de matériaux fluorescents (18, 19, 20) respectivement rouges, vert et bleu flamboyants. Les espaces entre les cloisonnements sont séparés dans plusieurs cellules par des cloisonnements transversaux (24R, 24G, 24B) dont les hauteurs diffèrent selon les quantités d'impuretés gazeuses émises respectivement par les trois types de matériaux fluorescents. Par exemple, si le matériau fluorescent (20) bleu émet plus d'impuretés gazeuses que les autres matériaux fluorescents (18, 19), son cloisonnement transversal (24B) sera plus bas que ceux des autres (24R, 24G) pour offrir un passage d'évacuation plus large.
