Abstract
A disclosed method of manufacturing an image display element structure includes a coating step of coating a substrate surface including a plurality of recessed portions arranged at predetermined intervals, with a coating material that is plastic-deformable, in such a manner as to maintain spaces in the recessed portions; and an expanding step of forming gaps in the coating material coating the substrate surface by expanding gas in the spaces, wherein the gaps correspond to the recessed portions; and a peeling step of peeling off the coating material in which the gaps have been formed, from the substrate surface.
