Color conversion filter substrate, color conversion type multicolor organic EL display having the color conversion filter substrate, and methods of manufacturing these

摘要

A color conversion filter substrate includes a transparent support substrate; color conversion filter layers formed of a resin film containing a fluorescent colorant and formed on the support substrate in a desired pattern; a polymeric film layer formed of a transparent material for covering the support substrate and having a flat surface; a transparent inorganic film layer formed on the polymeric film layer; and a transparent electrode layer formed on the inorganic film layer. The inorganic film layer is formed of a single layer, and has a refractive index n smaller than that of the transparent electrode layer with respect to light with a wavelength lambda in a range from 450 nm to 500 nm, and has a thickness d defined by nd=slambda/2, wherein s is a natural number.
