The present disclosure relates to a polarization film having a black strip for applying to a patterned retarder type 3D display device. The present disclosure suggests a polarization film for a patterned retarder type display device comprising: a polarization base film; a upper base film disposed on a upper surface of the polarization base film; a lower base film disposed on a lower surface of the polarization base film; and a black strip formed one of a upper side of the polarization base film and a lower side of the polarization base film. According to the present disclosure, the 3D display device can be manufactured in the simple processing and can reduce 3D cross-talk problem by having the double black strip structure.
