An method of forming buried wiring lines makes it possible not to limit usable materials for an insulative plate to those having excellent heat resistance and to improve the corrosion resistance of the terminals provided for the buried wiring lines. The surface of an insulative plate is selectively etched using a mask formed on the surface, thereby forming grooves in the surface. A metallic nanoparticle ink is placed over the whole surface of the plate to fill the grooves with the ink, where the mask is being left. The ink is heated for preliminary curing to form a metallic nanoparticle ink film. The part of the film placed on the mask is selectively removed by detaching the mask, thereby leaving the remainder of the film in the grooves. The remaining film in the grooves is heated for main curing, thereby forming desired buried wiring lines.

In order to suppress color tint during display of black, chromaticity is changed when black is displayed while maintaining chromaticity when white is displayed. For this purpose, the pigment to be dispersed in a color resist is adjusted in particle size and concentration. Such adjustment is so performed that the chromaticity difference between displayed white and black becomes 0.01 or smaller in the x-y chromaticity coordinates by varying the transmissivity of color pixels during display of black. With such a structure, successfully provided is a color liquid crystal display capable of preventing color tint in displayed black, while keeping white chromaticity at the desired level.
