Abstract: An optical laminate includes a wavelength selective reflective element, and an absolute phase adjustment layer which is provided on at least one surface side of the wavelength selective reflective element and has optical isotropy, and in which a first region having a first optical path length and a second region having a second optical path length different from the first optical path length are arranged in a pattern with a diffraction grating-like period. The optical laminate reflects light in the specific reflection wavelength region by the wavelength selective reflective element, of light incident from the absolute phase adjustment layer side. In the optical laminate, light which enters the first region of the absolute phase adjustment layer and is reflected by the wavelength selective reflective element and light which enters the second region and is reflected by the wavelength selective reflective element interfere with each other.
