EVALUATION METHOD OF IMAGE CLARITY OF OPTICAL LAMINATED BODY, AND OPTICAL LAMINATED BODY

To provide a method that objectively evaluates image clarity of an optical laminated body, and to provide the optical laminated body that is excellent in the image clarity.SOLUTION: A method is configured to measure a thickness of an optical laminated body every interval a(μm) by a stylus type surface shape measurement, and, when the thickness of the optical laminated body in a distance d1-a(μm) from a measurement start position is h[a]n(μm), the thickness of the optical laminated body in a distance d1(μm) from the measurement start position is h[a]n+1(μm), the thickness of the optical laminated body in a distance d1+a(μm) from the measurement start position is h[a]n+2(μm), a difference between h[a]n and h[a]n+1 is ΔD[a]n(μm), and a difference between hn+1 and hn+2 is ΔD[a]n+1(μm), evaluate image clarity of the optical laminated body on the basis of a sum total X[a](μm) of absolute values of ΔD[a]n and ΔD[a]n+1 satisfying ΔD[a]n>0 and ΔD[a]n+1
