Title: TRANSPARENT SUBSTRATE LAMINATE MANUFACTURING METHOD AND AERIAL IMAGE DISPLAY DEVICE MANUFACTURING METHOD
Abstract:
A transparent substrate laminate manufacturing method for manufacturing a transparent substrate laminate by laminating transparent substrates each having a mirror formed on at least one surface comprises a laminated product forming step (S11), and a pressurization and hardening step (S12). In the laminated product forming step, a laminated product obtained by laminating at least one transparent block obtained by previously laminating and bonding a plurality of transparent substrates, and at least another transparent substrate via a bonding agent such that a predetermined parallelism between the mirrors is ensured is formed. In the pressurization and hardening step, the laminated product is pressurized by flat surfaces of pressurization members disposed on both sides in the lamination direction of the laminated product to harden the adhesive.
