Composition for the production of a black matrix, process for producing a black matrix and plasma display panel comprising such a black matrix

Abstract

The composition for a black matrix, which does not include a mineral binding and/or sintering agent, preferably contains a pigment chosen from: i) an iron chromium aluminium mixed oxide, ii) an iron chromium nickel cobalt mixed oxide and iii) an iron chromium cobalt aluminium mixed oxide or a mixture of iron, chromium, cobalt and aluminium oxides. The invention also relates to a plasma display panel comprising a first tile (2) and a second tile (4) facing each other, enclosing a discharge space, and an array of discharge cells at the intersection of electrodes covered with a dielectric layer (6, 8, 12, 14), at least one of the tiles having a black matrix (30) embedded beneath a dielectric layer (6), the black matrix (30) consisting of an opaque material, at least part of which is incorporated into the said dielectric layer (6).
