Abstract

A flexible display substrate mother board and a method of manufacturing a flexible display substrate are provided. The method includes: forming a heating pattern layer on a support substrate, wherein the heating pattern layer includes a plurality of regional blocks spaced apart from each other; forming a flexible substrate on the substrate provided with the heating pattern layer, and forming display elements on the flexible substrate; and heating the flexible substrate by utilization of the heating pattern layer, cutting the flexible substrate, stripping the flexible substrate corresponding to the regional block from the support substrate, and forming flexible display substrates. The method can avoid the damage of the display elements on the flexible substrate when the flexible substrate and the support substrate are separated from each other, and avoid uneven separation.
