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: A) uniformly dispersing nanosized or microsized particles in a molten polymer matrix; B) 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, thereby orienting the nanosized or microsized particles in parallel with a surface of the polymer or plastic sheet; C) stretching the polymer or plastic sheet between the glass transition temperature and the melting point to form a polymer or plastic film, 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; D) coating the polymer or plastic film with an organic film to flatten a surface of the flexible display substrate; and E) performing heat treatment to cure the organic film.
