Abstract:
A color-converting filter substrate, comprising:a transparent supporting substrate; at least one color-converting filter layer formed of a resin film containing fluorescent colorant, said filter layer being formed in a desired pattern on the supporting substrate; a transparent polymeric film layer for covering the color-converting filter layer to form a flat surface; a single transparent inorganic film layer formed on the polymeric film layer; and a transparent electrode layer formed in at least one electrically independent region on the inorganic film layer; wherein for a wavelength &lgr; in a range from 450 nm to 500 nm inclusive, a refractive index of the inorganic film layer is lower than a refractive index of the transparent electrode layer, and a thickness d of the inorganic film layer satisfies a relationship nd=s&lgr;/2, wherein n is a refractive index of the inorganic film layer to light of the wavelength &lgr;, and s is a natural number.
