Abstract: A combiner 12 includes a cholesteric liquid crystal layer 17 that imparts an optical effect to light, and a cholesteric liquid crystal layer carrier 18 of a plate shape that is an optical functional layer carrier having a plate surface with the cholesteric liquid crystal layer 17 disposed thereon, being subjected to biaxial stretching in such a manner that one of two intersecting directions along the plate surface is a low stretching direction in which a stretch ratio is relatively low and that the other is a high stretching direction in which the stretch ratio is relatively high, and being subjected to biaxial deformation to have the plate surface deformed into a curved shape in such a manner that a large elongation amount direction in which the amount of elongation by deformation is relatively large matches the low stretching direction and that a small elongation amount direction in which the amount of elongation by deformation is relatively small matches the high stretching direction.
