摘要： PURPOSE:To obtain the light-shielding pattern excellent in adhesion to a substrate, weatherability of the coating film and light shielding property by forming the pattern with a specified grain group of the substance having a layer lattice structure. CONSTITUTION:A light-shielding pattern layer 2 formed on a transparent substrate 1 consists of a grain group of the substance having a layer lattice structure. The diameter of the light-shielding grain is controlled to =2 kinds of the substances is used, and the substance can be combined with pigment or dye.

摘要： PURPOSE:To provide a clear display image for an image display which is formed with absorbance matrixes in a complex configulation such as a black matrix for a color cathode ray tube, a crystal and an optical filter for a plasma display. CONSTITUTION:An image display has picture element areas arranged at spaces and a transparent plate 1 to which adjacent absorbance matrixes are adhered on one face, graphite particle layers 2a and crystallized carbon black particle layers 2b being formed on the adhesion face sides of the absorbance matrixes to the transparent plate and on the opposite sides, respectively. The absorbance matrix comprises steps of forming a stencil on the surface of the transparent plate into an absorbance matrix negatively patterned shape, of applying thereon slurry of absorbance material substancially composed of graphite particles and solidifying it into a coating, of applying slurry of absorbance material composed of crystallized carbon black particles on the coating and solidifying it into a coating and of removing the coating excluding the coating directly adhered to the surface of the transparent plate.
