Abstract
A color liquid crystal display device comprising a color filter having a structure including a black matrix BM formed on a transparent substrate, a colored layer FIL colored into at least three primary colors and formed by thermal dye transfer technology, a protective area for protecting against dye diffusion filling the gaps between the colored patterns, a transparent protective overcoat PSV2 formed on the colored layer and a transparent conductive electrode ITO2 formed on the transparent protective overcoat. The protective area against dye diffusion is constituted of a not-colored part FIL(T) of a dye receiving layer, protective overcoats PSV2 and PSV3, or of a black matrix with a high heat resistance. Moreover, the protective film is made from a metal-containing organic silicon compound that can be hardened by light or heat.
