A light-shielding film, and a liquid crystal display device including the light-shielding film, and a material suitable for forming the light-shielding film. The light-shielding film includes at least a film prepared from an inorganic insulating material and fine particles of metal and/or semi-metal dispersed in the insulating material film. The liquid crystal display device includes a display pixel electrode array substrate, a counter substrate, and a liquid crystal layer interposed between the two substrates. The light-shielding film is formed on the display pixel electrode array substrate of the liquid crystal display device.
