Abstract
A color conversion material comprises a high-molecular material having a light transmittance of at least 90% in a visible light region, a fluorescent dye contained therein, and a fluorescent pigment particle dispersed therein. The wavelength of unconverted light incident on the color conversion material is up to 520 nm, the light emission maximum wavelength of the conversion material is at least 580 nm upon incident light conversion, and the conversion efficiency of at least 10% is obtained.
