OPTICAL LAMINATE, POLARIZING PLATE, AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optical laminate capable of sufficiently suppressing the occurrence of interference fringes and curls, reducing the film thickness of a hard coat layer, and preventing an increase in manufacturing costs.SOLUTION: An optical laminate includes a hard coat layer on one surface of a light-transmissive base material, and a low refractive index layer on the hard coat layer. The low refractive index layer has a concave-convex shape on the surface; and when the average inclination angle of a concave-convex part is &thetas;a, and Kurtosis of the concave-convex is Kr, the concave-convex shape satisfies the following formula: 0.01°≤&thetas;a≤0.10°, 1≤Kr≤3.
