A process for manufacturing a display device, an optical device or an illuminating device includes casting a polyamide solution onto a base at temperature below 200° C. to obtain a film, heating the film on the base at temperature sufficient to make the film solvent resistant and obtain a polyamide film, forming on a surface of the polyamide film one of a display element, an optical element and an illumination element to form a display device, an optical device or an illumination device, and de-bonding the base from the display device, the optical device or the illuminating device. The polyamide solution comprises a solvent, an aromatic polyamide dissolved in the solvent, and a multifunctional epoxyde, where the aromatic polyamide comprises at least one functional group that reacts with an epoxy group, the aromatic polyamide comprises a first repeat unit of formula (I) and a second repeat unit of formula (II) |
