| 主权项 | 1. A folder type polarizing film for OLEDs, the film comprising: a polarizer; a transparent support attached to an upper surface of the polarizer, the transparent support being a cycloolefin polymer film; and a compensation film attached to a lower surface of the polarizer, the compensation film being a cycloolefin polymer having a phase difference of λ/4 relative to a polarization axis of the polarizer, wherein: the polarizing film as a whole has a tensile strength of about 13 to about 20 kgf/mm2, and a folded portion of the polarizing film is not whitened after being folded to a radius of curvature of 5 mm about 1,000 or more times. | ||
