Claim 0:
1. A method of manufacturing a flexible substrate, comprising:
dissolving a flexible substrate in a solvent of N-methylpyrrolidone, wherein the flexible substrate comprises a sulfur-containing diamine monomer and a dianhydride monomer, and the flexible substrate dissolved in the solvent has a solid content of 5-30%; and
performing a high temperature polymerization to form a polyamide film under an inert atmosphere, wherein the inert atmosphere is nitrogen atmosphere, a curing temperature ranges from 200° C. to 400° C., and a molar ratio of the sulfur-containing diamine monomer and the dianhydride monomer is controlled to obtain the flexible substrate having different refractive indexes;
wherein the flexible substrate comprises a glass substrate, a first flexible base layer disposed on the glass substrate, a second flexible base layer disposed on the first flexible base layer, and a third flexible base layer disposed on the second flexible base layer.
