Claim 0:
1. An optical laminate comprising
a circular polarizing plate having a retardation plate and a polarizer, and an antireflection layer having a surface reflectance of 2% or less, wherein the retardation plate has reverse dispersion characteristics,
a wavelength at which a spectral reflectance of the antireflection layer at an incidence angle of 5° exhibits a minimum value is 500 to 545 nm, such that a reflection light of the antireflection layer has a reddish tint, wherein the reddish tint of the reflection light of the antireflection layer at least partially offsets a bluish tint of a reflection light of the retardation plate,
the antireflection layer is provided on the polarizer side of the circular polarizing plate; and
L * of light incident from the antireflection layer side in a specular component included
(SCI) mode is 20 or less, and a saturation is 20 or less.
