Abstract

Embodiments relate to a protective film for a polarizer, a polarizing plate, and a display device comprising the same. The protective film for a polarizer according to the embodiments is improved in mechanical strength and minimized in rainbow strains by minimizing the difference in the orientation angle between the center and the edge of the film while generating a difference in the strengths in the longitudinal/transverse directions of the film. Hence, it can be advantageously used as a protective film for a polarizer.
