Polarizing film and display device including the same

PROBLEM TO BE SOLVED: To provide: a polarizing film which has excellent orientation of a dichroic dye at high-temperature elongation without migration of the dichroic dye, and has high polarization efficiency and transmittance and excellent workability; a display device including the polarizing film; and a composition for the polarizing film.SOLUTION: A polarizing film 20 includes a high-temperature elongation film of a polyolefin resin 21 and a dichroic dye 22, and the polyolefin resin 21 has zero shear viscosity (η) ranging from about 2600 Pa s to about 17400 Pa s at a temperature of 210°C (±3°C).SELECTED DRAWING: Figure 1
