Abstract

The present application provides a method of fabricating a quantum dot color film substrate, by utilizing a characteristic that a dispersion including dye molecules, quantum dots and polymers in which difference of surface free energy of the dye molecules and the quantum dots cause phase separation of the quantum dots and the dye molecules during a solvent evaporation process, red and green quantum dot light filter films of bilayer structure of quantum-dye molecule phase separation are formed, the red and the green quantum dot light filter films respectively have the red and the green quantum dots in the upper layers, and the red and the green dye molecules in the lower layers, so as to have effects of bilayer films structure of the quantum dot film added with the light filter film, in comparison to the bilayer films structure of the quantum dot film added with the light filter film, the bilayer structure of the red and the green quantum dot light filter films do not have interface effect that the interface effect causing light loss is reduced; simultaneously, for completing the phase separation only requires the solvent evaporation process, the fabrication process is simpler than the conventional bilayer films structure of the quantum dot film added with the light filter film.
