1. 3D glasses comprising:
a right-eye polarizer; and
a left-eye polarizer,
the right-eye polarizer and the left-eye polarizer each comprising a polarizing plate and a first λ/4 plate,
at least one of the right-eye polarizer or the left-eye polarizer comprising a phase difference layer on or behind a back surface side of the polarizing plate,
wherein the phase difference layer is a positive C plate or a negative C plate providing a phase difference of 5 nm or less in an in-plane direction, and
a phase difference introduced by the right-eye polarizer in a thickness direction at a wavelength of 550 nm is different from a phase difference introduced by the left-eye polarizer in the thickness direction at a wavelength of 550 nm.
