Abstract
Adhesive layers are formed on the two opposing surfaces of a transparent support. At least one of the adhesive layers is made of a material of which the cured state changes by application of external force, such as a photocurable resin. A separator on the adhesive layer is peeled off, and the adhesive layer is irradiated with light. A lens sheet is then pressed against the adhesive layer. The adhesive layer is cured to a degree of hardness with which the adhesion state between lens sheet and the adhesive layer no more changes. In this way, a laminate film of the lens sheet fixed to the transparent support via the adhesive layer is obtained. The laminate film is bonded to a polarizing plate on the viewer's side of a liquid crystal display element via the other adhesive layer.
