Abstract
The present invention relates to a white and color photoexcitation light emitting sheet comprising a substrate, a light source formed on the substrate, and a white and color photoexcitation light emitting layer capable of converting a light emitted from the light source into a light having a different wavelength, where the white and color photoexcitation light emitting layer is fabricated by mixing a matrix polymer, white and color photoexcitation light emitting materials and a solvent, spinning the resulting mixture to prepare an ultrafine composite fiber layer of the matrix polymer/photoexcitation light emitting materials, and thermocompressing the ultrafine composite fiber layer; and a method for fabrication thereof. The white and color photoexcitation light emitting sheet according to the present invention has uniform brightness and color coordinates and exhibits high color reproducibility.
