するものは少ない。[Prior Art] In recent years, full-color liquid crystal display devices have already been put to practical use, and the reproducibility of one color has been improved to the point that it is comparable to that of a cathode ray tube (CRT). As a full-color liquid crystal display device with excellent color reproducibility, there is a color filter method in which a color filter is provided inside or outside a liquid crystal cell and the liquid is used as an optical shutter. A color mosaic pattern of the three primary colors of red, green, and blue is arranged on a substrate to form a filter, and by providing a light shielding area around the color tod, contrast is increased and image quality with high clarity is obtained. Although there are many examples of using carbon as a light-shielding pigment, there are few that satisfy the required quality in terms of dispersibility and smoothness.
