Abstract

The present invention relates to polarizing glasses, and more specifically, to polarizing glasses comprising: a λ/4 phase difference layer for transforming circularly polarized light into linearly polarized light; an auxiliary phase difference layer having specific optical characteristics for transforming the light which is not linearly polarized by the λ/4 phase difference layer into linearly polarized light; and a polarizer for passing the light emitted from the auxiliary phase difference layer. The polarizing glasses transform the circularly polarized light received through an inclined plane into linearly polarized light in known polarizing glasses, thereby improving known cross torque due to light leakage (simultaneous incidence of left and right lights into one side).
