Optical laminate with polarizing film

An optical laminate comprising a polarizing film comprised of a polyvinyl alcohol-based resin having oriented iodine, and a sub-laminate, wherein:

• the sub-laminate comprises at least an optically transparent adhesive layer and an optical film, wherein the optical film is bonded to a first surface of the polarizing film through the optically transparent adhesive layer;
• the polarizing film exhibits a property that a value expressed by the following formula:
• Aa×(Is/Ia), is 0.53 or more, where:
• Aa represents an absorbance in an absorption axis direction of the polarizing film at a wavelength of 480 nm;
• Ia represents a value obtained by integrating, over an entire interval in a thickness direction of the polarizing film, a distribution of integrated intensities in the thickness direction of the polarizing film, wherein each of the integrated intensities is obtained by integrating a Raman spectrum of the polarizing film in a wavenumber interval of 90 cm−1 to 120 cm−1;
• and
• Is represents a value obtained by integrating, over the entire interval in the thickness direction of the polarizing film, a distribution of integrated intensities in the thickness direction of the polarizing film, wherein each of the integrated intensities is obtained by integrating, in a wavenumber interval of 90 cm−1 to 120 cm−1, Raman scattering of I3− ions which exist in a region of the polarizing film ranging from the first surface to 1 μm inward in the thickness direction thereof, and oriented in the absorption axis direction of the polarizing film;
• and
• the sub-laminate has a thickness of 60 μm or more.
