Abstract:
Provided is an optical laminate in which color unevenness resulting from an antireflection film is prevented, the optical laminate being thin and excellent in neutral black reflection hue. The optical laminate includes: a first substrate; a second substrate arranged on one side of the first substrate; an antireflection film arranged between the first substrate and the second substrate; and a resin layer arranged between the first substrate and the second substrate to cover the antireflection film, in which: the antireflection film includes a polarizer and a retardation layer bonded to the polarizer; and the resin layer has a storage modulus of elasticity at 25° C. of 1×106 Pa or more.
