Abstract
A color-converting-function-possessing color filter and a method for its manufacture are disclosed. A simplified manufacturing process is provided that makes possible highly detailed patterning. The method of manufacturing the color-converting filter comprises a step of forming color filter layers on a transparent substrate, a step of forming a colorant layer containing a color-converting colorant on the color filter layers, and a step of exposing the colorant layer via the transparent substrate and the color filter layers using colorant-decomposing light, thus forming color-converting layers in positions corresponding to the color filter layers. In usage, a layered body consists of a transparent substrate, color filter layers and a colorant layer as a color-converting-function-possessing filter.
