Disclosed herein is a method of manufacturing a flexible display substrate having low moisture permeability and low oxygen permeability, the flexible display substrate being mounted with an organic device. The method includes the steps of uniformly dispersing nanosized or microsized particles in a molten polymer matrix (S101) forming the molten polymer matrix dispersed with the nanosized or microsized particles into plate-shape molten polymer, and then extruding the plate-shape molten polymer between two extruding rollers to form a polymer or plastic sheet (S103), thereby orienting the nanosized or microsized particles in parallel with a surface of the polymer or plastic sheet, stretching the polymer or plastic sheet between the glass transition temperature and the melting point to form a polymer or plastic film (S105), thus improving exfoliation of the nanosized or microsized particles, and orienting the nanosized or microsized particles to a higher degree in parallel with a surface of the polymer or plastic film, coating the polymer or plastic film with an organic film to flatten a surface of the flexible display substrate (S107) and performing heat treatment to cure the organic film (S109). |
