Claim:
1. Polarizing glasses, comprising an area for a left eye and an area for a right eye, into which an image signal enters, wherein each of the areas for the left eye and for the right eye comprise an optical anisotropic layer and a polarizer respectively, wherein the optical anisotropic layer comprises at least two optical anisotropic films, and wherein the optical anisotropic layer has a value calculated by Formula 1 in a range from 50 nm to 400 nm, and a value calculated by Formula 2 in a range from 0.1 to 3: where X is a sum of refractive indices for the at least two optical anisotropic films in the direction of an in-plane slow axis of the optical anisotropic layer, Y is a sum of refractive indices for the at least two optical anisotropic films in the direction of an in-plane fast axis of the optical anisotropic layer, Z is sum of refractive indices for the at least two optical anisotropic films in the direction in a thickness of the optical anisotropic layer, and D is a sum of thicknesses for the at least two optical anisotropic films of the optical anisotropic layer.
