Patent ID: 8520331

Claim:
A method for manufacturing a color filter, comprising, in the order recited, the steps of: forming a plurality of banks comprised of resin on a transparent substrate; forming, on the transparent substrate between respective banks of the plurality of banks, a plurality of color filter layers comprised of polysiloxane material and pigments dispersed in the polysiloxane material, and having respective colors, so as to form an assembly of the transparent substrate, the plurality of banks and the plurality of color filter layers; treating the assembly with oxygen plasma; treating the assembly with fluorine plasma; and forming at least one color conversion layer having a color respectively on the plurality of color filter layers by an inkjet method, wherein the pigments are organic pigments, and wherein the plurality of color filter layers are formed from polysiloxane material and organic pigments dispersed in the polysiloxane material, and wherein the polysiloxane material is provided as a precursor thereof, and forming the plurality of color filter layers includes the steps of: affixing a dispersion of the organic pigment and the precursor of the polysiloxane material to the transparent substrate by inkjet printing or screen printing; and forming the polysiloxane material by hydrolytic condensation or hydrolytic co-condensation of the precursor of the polysiloxane material.
