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.
Claims19
A color conversion layer, comprising:
- a fluorescent medium for converting light emitted from an emitting medium to light having a longer wavelength,
- particles of an organic material and/or an inorganic material with a coating layer formed from a material suppressing extinction of the fluorescent medium caused by the particles, and
- a binder resin in which the fluorescent medium and the particles with the coating layer are dispersed,
- wherein the fluorescent medium converts light in a blue range emitted from the emitting medium to light having a longer wavelength, and the color conversion layer has a haze value of 65 to 85%.
