Claim:
1. A manufacturing method of a color filter (CF) substrate, comprising the following steps: (11) placing a growth substrate in a chemical vapor deposition reactor and introducing a mixed gas of a carbon source gas and a carrier gas to carry out a reaction under the conditions of 900-1120° C. and 110-5000 KPa for 1-60 min so as to grow a graphene film on a single side of the growth substrate, wherein the graphene film has a thickness that is greater than 0.8 nm and less than or equal to 10 nm, transmittance of visible light being 80-97%, and surface resistance being 30-500Ω/□; (12) coating a transfer medium layer on the graphene film to obtain a combination of transfer medium layer/graphene film/growth substrate; (13) dipping the combination of transfer medium layer/graphene film/growth substrate in a growth substrate corrosive liquid to remove the growth substrate so as to obtain a combination of transfer medium layer/graphene film; (14) providing a CF substrate body, wherein the CF substrate body comprises a glass substrate and a color resist layer formed on the glass substrate, wherein the color resist layer comprises a photoresist that changes property from being insoluble to a photoresist developer to being soluble to the photoresist developer, or from being soluble to a photoresist developer to being insoluble to the photoresist developer, upon exposure to light; (15) positioning the combination of transfer medium layer/graphene film on the CF substrate body to proceed with transferring in room temperature so as to obtain a combination of transfer medium layer/graphene film/CF substrate body; and (16) placing and washing the combination of transfer medium layer/graphene film/CF substrate body in a transfer medium layer removing solvent to remove the transfer medium layer so as to obtain a graphene film on the CF substrate body and thus forming a transparent conductive layer on the CF substrate body.
