Title: OPTICAL LAMINATE
Abstract:
The present invention provides an optical laminate that can be manufactured easily and that enables a wavefront of reflected light arising from a wavelength selective reflection element to be arbitrarily designed. The optical laminate is provided with: a wavelength selective reflection element provided with a reflection layer for selectively reflecting light in a specific reflection wavelength region; and an absolute phase adjustment layer provided on at least one surface side of the wavelength selective reflection element and having optical isotropy, wherein the absolute phase adjustment layer has an in-plane distribution of optical path length in a film thickness direction by having an in-plane distribution of refractive index and/or film thickness.
