Apparatus for manufacturing a color conversion filter

Abstract

An apparatus for manufacturing a color conversion filter, having a color filter layer on a transparent substrate. A coloring matter layer containing color conversion coloring matter and an optical radical generating agent are formed on the substrate and the filter layer. The coloring matter layer is exposed to coloring matter decomposition light applied through the substrate and the filter layer. The coloring matter layer also is exposed to auxiliary ultraviolet light applied from the side of the coloring matter layer. This forms a color conversion layer at a position corresponding to the filter layer. The optical radical generating agent is heat vaporized. The color conversion coloring matter is decomposed by light whose wavelength is outside a range that the color filter layer transmits. The coloring matter decomposition light includes a wavelength component that decomposes the color conversion coloring matter. The color conversion layer emits, through wavelength profile conversion, light that the color filter layer transmits.
