PROBLEM TO BE SOLVED: To provide a high-temperature oxidation-resistant P capable of suppressing black discoloration due to oxidation even when subjected to heat treatment in a high-temperature oxidizing atmosphere. Provided are a black pigment for DP black stripe, a dispersion using the same, and a PDP. Provided are a black pigment for a PDP black stripe, which solves process matching and improvement in contrast, a dispersion liquid using the same, and a PDP. A TiN x O y or Ti n O 2n-1 (where, 0.2 ≦ x ≦ 1.4, 0.1 ≦ y ≦ 1.8, 1 ≦ n ≦ 1 0. ), The surface of the lower titanium oxide powder is silica, alumina, titania, zirconia, magnesia, P coated with one or more compounds selected from the group consisting of niobium oxide, tantalum oxide and zinc oxide It is a black pigment for DP black stripes. |
