Claim 1:
2. The 3D glasses according to claim 1,
wherein the right-eye polarizer and the left-eye polarizer satisfy the following formula (1):

|Rth1−Rth2|≥120 nm  (1)

where Rth1 is the phase difference introduced by the right-eye polarizer or the left-eye polarizer in the thickness direction at a wavelength of 550 nm, whichever is greater; Rth2 is the phase difference introduced by the right-eye polarizer or the left-eye polarizer in the thickness direction at a wavelength of 550 nm, whichever is smaller; and Rth1>Rth2.
