A high boiling-point solvent, included in a fluorescent color conversion film, suppresses degradation in color conversion characteristic by compensating for a decrease in dielectric constant due to solidification of the matrix system. The fluorescent color conversion film of the present invention includes, in addition to the high boiling point solvent, organic fluorescent dyes, which absorb light in a near ultraviolet to visible light region and emit visible light of a different wavelength, and a matrix resin bearing the organic fluorescent dye. The high boiling point solvent has a boiling point of 150° C. or higher and a vapor pressure of 5 mmHg or lower at the temperature of 20° C. The fluorescent color conversion film is useful in a fluorescent color conversion filter, which itself is useful in light-emitting devices, such as self-emitting multi-colored- or full colored-displays, display panels and backlights. |
