Patent ID: 7381504

Claim:
A method of manufacturing a color conversion filter, comprising the steps of: forming a color filter layer on a transparent substrate; forming a coloring matter layer containing color conversion coloring matter and an optical radical generating agent on the color filter layer; exposing the coloring matter layer to coloring matter decomposition light that is applied through the transparent substrate and the color filter layer, and to auxiliary ultraviolet light that is applied from the side of the coloring matter layer, and thereby forming a color conversion layer at a position corresponding to the color filter layer; and vaporizing the optical radical generating agent by heating it, wherein the color conversion coloring matter is decomposed by light in a wavelength range that is outside of a wavelength range of light that the color filter layer transmits; wherein the coloring matter decomposition light includes a wavelength component that decomposes the color conversion coloring matter; and wherein the color conversion layer emits, through wavelength profile conversion, light that the color filter layer transmits.
