Abstract

Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung eines Farbkonversionsfilters und ein Farbfilter mit Farbkonversionsfunktion zu schaffen, wodurch das Herstellungsverfahren vereinfacht werden kann und eine sehr detaillierte Musterbildung (patterning) möglich ist. DOLLAR A Erfindungsgemäß wird dazu ein Verfahren zur Herstellung eines Farbkonversionsfilters vorgeschlagen, das gekennzeichnet ist durch eine Stufe der Bildung von Farbfilterschichten auf einem transparenten Substrat, eine Stufe der Bildung einer Farbstoffschicht, die einen Farbkonversionsfarbstoff enthält, auf den Farbfilterschichten und eine Stufe der Belichtung der Farbstoffschicht durch das transparente Substrat und die Farbfilterschichten unter Verwendung eines farbstoffzersetzenden Lichts, wodurch Farbkonversionsschichten in Positionen gebildet werden, die den Farbfilterschichten entsprechen. Verwendung eines Mehrschichtkörpers, bestehend aus einem transparenten Substrat (1), Farbfilterschichten (2) und einer Farbstoffschicht (3) als ein Filter mit Farbkonversionsfunktion.The object of the invention is to provide a method for producing a color conversion filter and a color filter with color conversion function, whereby the manufacturing process can be simplified and a very detailed patterning (patterning) is possible. DOLLAR A According to the present invention, there is provided a process for producing a color conversion filter characterized by a step of forming color filter layers on a transparent substrate, a step of forming a dye layer containing a color conversion dye on the color filter layers and a step of exposing the dye layer through the transparent substrate and the color filter layers using dye-decomposing light, whereby color-conversion layers are formed in positions corresponding to the color filter layers. Use of a multilayer body consisting of a transparent substrate (1), color filter layers (2) and a dye layer (3) as a filter with color conversion function.
