The present invention provides a substrate for flexible displays, a method for producing the same, and a flexible display. The substrate for flexible displays comprises a resin composition layer containing an inorganic layered compound and a resin, wherein the amount of the inorganic layer compound is not less than 10 weight % and not more than 70 weight % based on the total amount of the resin and the inorganic layer compound. The method for producing a substrate for flexible displays comprises applying a mixture of a solvent, an inorganic layer compound, and a resin to a plate, drying the mixture, and peeling off the resulting layer from the plate. The display comprises the above substrate for flexible displays and electrodes.
