Abstract
A fluorescent conversion filter includes a fluorescent conversion film which facilitates converting light from a wavelength region between near ultraviolet and green to light in the red region which can be finely patterned. A color display device can be produced which includes the fluorescent conversion filter. The fluorescent conversion filter includes a fluorescent conversion film and a light absorption film on the display side surface of the flourescent conversion film. The flourescent conversion film has an absorbance of 1 or less in the wavelength region between 450 nm and 520 nm. The light absorption film has an absorbance of greater than I in the wavelength region between 450 nm and 520 nm. The fluorescent conversion film contains a photo-curing resin or a photo- and thermo-setting resin, that contains an acrylate polymer, a methacrylate polymer or an acrylate-methacrylate copolymer as its main component.
