A polyimide polymer includes one or more aromatic dianhydride monomers and one or more aromatic diamine monomers as recited herein. A method for making a flexible display device includes preparing a polyimide solution including a polyimide polymer dissolved in a solvent, coating a substrate with the polyimide solution, heating the coating to evaporate the solvent and form a polyimide layer, forming a display device layer on the polyimide layer, dicing through the display device layer and through the polyimide polymer layer, and delaminating the layer from the substrate to form the flexible display device. A flexible display device can include a polyimide polymer backing layer and a display device disposed on the polyimide polymer backing layer, the polyimide polymer including one or more aromatic dianhydride monomers and one or more aromatic diamine monomers as recited herein.
