Manufacturing method and manufacturing apparatus for hollow structure of image display element

An image display element structure manufacturing apparatus comprising:

• a coating unit configured to coat a substrate surface comprising plural recessed portions arranged at predetermined intervals, with a plastic-deformable material, in such a manner as to maintain spaces in the recessed portions;
• an expanding unit that deforms, by expanding gas in the spaces, the plastic-deformable material that is coating the substrate, to form plural gaps in the plastic-deformable material, the plural gaps being in correspondence with the respective plural recessed portions in the substrate surface, wherein
• the expanding unit reduces pressure on a surface of the plastic-deformable material coating the substrate surface to expand the gas in the spaces in the recessed portions, an expansion force of the gas causing the gaps to form in the plastic-deformable material coating the substrate surface;
• and
• a peeling unit configured to peel off the plastic-deformable material in which the gaps have been formed, from the substrate surface.
