METHOD FOR FABRICATING PLASTIC SUBSTRATE

摘要

PURPOSE: A plastic substrate fabricating method is provided to minimize the hydrogen content and the porosity of a barrier layer by local heat treatment without influencing on a plastic substrate, thereby forming a uniform film to restrain the permeation of external oxygen and moisture and preventing the deterioration of a display system. CONSTITUTION: A plastic substrate fabricating method includes the steps of forming barrier layers(30) of silicon on a transparent plastic substrate(20), and carrying out local heat treatment for the barrier layer for removing the defects of the barrier layers caused by a plurality of dangling bond and porosity generated by the incomplete bonding between silicon and oxygen or nitrogen during the barrier layer stacking. A desiccant layer is interposed between the plastic substrate and the barrier layers.
