1. A method of manufacturing a flexible display substrate, comprising:
preparing a base layer on a substrate;
forming a plurality of cells on a top surface of the base layer, the plurality of cells being spaced apart from one another;
covering the plurality of cells on the top surface of the base layer with a film, the film comprising a first base layer and a first adhesive layer, the first adhesive layer being between the base layer and the first base layer to adhere the first base layer to the plurality of cells on the top surface of the base layer;
separating the plurality of cells, the base layer, and the film from the substrate; and
cutting the base layer and the film to form a plurality of flexible display substrates,
wherein the preparing of the base layer, the forming of the plurality of cells, and the covering of the plurality of cells are performed in stated order.
