A process for producing a color conversion filter

A process for producing a color conversion filter, characterized by the following steps: Forming color filter layers (2) on a transparent substrate (1); Forming a dye layer (3) containing a color conversion dye (CCM) on the color filter layers (2) and on the transparent substrate (1); and Exposing the dye layer (3) through the transparent substrate (1) and the color filter layers (2) through using farbstoffzersetzendem light, whereby the color conversion layers (4) are formed at positions corresponding to the color filter layers (2), respectively; wherein the color conversion dye (CCM) the transmitted wavelength range is decomposed by light outside of one of the color filter layers (2), wherein the farbstoffzersetzende light contains a wavelength range which decomposes the color conversion dye (CCM) and wherein the color conversion layers (4) emit light by wavelength distribution conversion light that is transmitted through the color filter layers (2).
