Patent ID: 7414354

Claim:
A color conversion filter substrate comprising: a transparent support substrate; and a pattern layer in a desired pixel pattern form, a first overcoat layer, and a first transparent inorganic thin-film layer stacked in that order on a surface of the transparent support substrate; wherein the first overcoat layer is at least partially formed of a reaction product prepared by a chemical reaction mainly based on hydrolysis of a starting material comprising at least one material selected from the group consisting of aminoalkyldialkoxysilanes, aminoalkyltrialkoxysilanes, and composites thereof; wherein a surface of the first transparent inorganic thin-film layer has an Ra (average roughness) value of not more than 5 nm and an Rmax (maximum roughness) value of not more than 80 nm; and wherein the pattern layer has a laminated structure comprising one or more types of color-patterned color filter layers, formed by disposing a colored resin film on the transparent support substrate and patterning the resin film in a desired pattern, and a color conversion layer containing a fluorescent material is provided on the color filter layers.
