Abstract
A color conversion layer is provided which is capable of converting light from an emitting medium effectively to light containing a ray having a longer wavelength and exhibits less deterioration so as to have a long lifetime. The color conversion layer comprising a fluorescent medium for converting light emitted from an emitting medium to light having a longer wavelength, and having a haze value of 50% to 95%. The color conversion layer can be made thin, since the layer can efficiently convert the color of light from an emitting medium. The processibility such as patterning thereof is then improved.
