ABSTRACT:
A method for fabricating multi-layer polymer thin film of an electro-optical device which has a qualified multi-layer by using photobleaching characteristics of polymer. A proper time of photobleaching only changes the chemical, mechanical and electrical characteristics of the surface of the thin film without having any influence on characteristics of the device, so that when the multi-layer thin film are formed, such a cracking due to a solvent or melting, cracking due to the difference of mechanical tensile strength between each layer can be prevented, thereby obtaining a clean multi-layer thin film.
