Claim 5:
6. The optical element according to claim 1,
wherein when the optical element is irradiated with light from a back surface side of the first polarizer,
a transmittance T2 of oblique light transmitted at an azimuthal angle of 45° and a polar angle of 60° through the second polarizer is 20% or lower relative to a transmittance T1, taken as 100%, of the light transmitted through a configuration without the first phase difference layer or the second phase difference layer, and a color difference Δxy between an azimuthal angle of 0° and an azimuthal angle of 45° with the polar angle fixed at 60° is 0.015 or less.
