Abstract:
1. A color-converting-function-possessing color filter, comprising: a transparent substrate; color filter layers of n types formed on said transparent substrate, wherein n represents an integer from 2 to 6; and a colorant layer containing at least one color-converting colorant formed integrally with and covering said color filter layers of the n types, said colorant layer being self-aligned with said color filter layers by means of exposure through said transparent substrate and said color filter layers; wherein said at least one color-converting colorant (i) absorbs light in part of the wavelength region of incident light, and emits light in a wavelength region different to the wavelength region of absorption, (ii) is decomposed by light transmitted by transparent substrate, but is not decomposed by light transmitted by color filter layers, and (iii) does not produce colored decomposition products when it is decomposed by light.
