PURPOSE:To provide a color filter excellent in contrast of images and heat resistance with low production cost, and to provide its production. CONSTITUTION:A metal oxide sol containing a coloring pigment is prepared by hydrolyzing a single material or mixture of metal compds. and adding a coloring pigment dispersion liquid. This sol is applied on a transparent substrate 1 to form a colored layer in a pattern according to the number of colors without giving a space. Then the colored layer is subjected to heat treatment to produce a xerogel film 2. Then metal particles are made to impregnate and adsorb to the xerogel film 2 by electroless plating to form a black matrix part 3 in a lattice or mesh state. |
