摘要： This dispersion liquid composition for black matrix comprises; manganese oxide having an average particle diameter in the range of 50 to 2000 nm, or solid solution of manganese oxide and ferric oxide having an average particle diameter in the range of 50 to 2000 nm and a manganese content in the range of 15 to 70% by weight; at least one kind of dispersing agent selected from a group of water-soluble acrylic resin, sodium salt, ammonium salt or potassium salt of water-soluble acrylic resin, and sodium salt, ammonium salt or potassium salt of polycarboxylic acid or ligninsulfonic acid or bisphenolsulfonic acid; and water, or a solvent mixture of water and an organic solvent compatible with water. By employing such a dispersion liquid composition for black matrix, light reflectivity of a light absorption layer of an interface with a panel is remarkably reduced. Accordingly, in a display device such as a color cathode ray tube, a display surface in which superposition of ambient light is difficult to occur is realized.
