ABSTRACT:
A luminescent screen for a picture display apparatus comprising a plate glass screen 1 and a luminophore layer 6 formed on the glass plate in depressions 4 that are surrounded by a black pigmented contrasted border layer 5. The luminescent screen has an optimum color purity and in particular off-color combinations on the surface of the layer of the respective color should be avoided and is undesirable. For this purpose, the invention provides that the luminous colors of the luminophore layer 6 comprising the luminous colors red (R), green (G) and blue (B) are applied to the screen glass plate 1 in a raster of line-like systematic arrangements by using a silk screening process. Luminescent screen according to the invention is employed as a flat plasma picture screen.
